Converting Decimals into Fractions and Percents

[noonelikesem99]

I knew it. Pero I forgot. Buti pinaalala. :))

[cjla1987]

what would 3.234543123123123123123 it started repeating 123...how would you solve that? thanks mbrandl

[mbrandl11]

@cjla1987

That's kind of a crazy one! If you do a search for "converting a repeating decimal to a fraction calculator" on Google you should see a tool at easycalculation(dot)com that will help.

By the way, yours work out to be: 53855143 / 16650000

I hope that helps! Keep working hard on your math! :-)

[cjla1987]

@mbrandl11 Thanks a lot mbrandl11!

[BriaNKiiD2K12]

@cjla1987 js thats a reccuring decimal :)

[MyMissBlueberry]

THIS ISNT HELPING

what about these kinds 0.027

[mbrandl11]

@MyMissBlueberry

With three decimal places it's thousandths, so 27/1000.

I hope that helps! :-)

[MoveRed]

much thanks made everything simple & clear

[JuiceBoxette]

I'm a substitute teacher just out of college with very little teacher-training (gonna go to grad school for my master's in edu and teaching certification), and was trying to figure out how to teach my 5th graders this tomorrow. This video was very helpful; thank you for posting! :)

[amwin67]

so on the 3 repeated would you put the nine under> would you do that with any number?

[mbrandl11]

@amwin67

Right, 3 repeating would be 3/9, which simplifies to 1/3. 4 repeating would be 4/9, 1 repeating would be 1/9 and so on.

Keep working hard on your math! :-)

[amwin67]

@mbrandl11 so 7 repeating would be 7/9 too?

[mbrandl11]

@amwin67

You got it!

[ProfessorWhiskerz]

Thanks for the video, this is very helpful for my studies!

[steelersfan3898]

You are the man! Every teacher I have had for math explains everything in such a difficult way. My teacher at Connections Academy was explaining how to turn repeating decimals into fractions and was telling us to first make it equal to a variable then divide each side by something... It was HORRIBLE! I decided to look it up online and thank God I found this. Thank you so, so much for taking the time to do this for kids. I really appreciate it and I am sure others do as well. Please keep posting

[Alexiablack101]

where did u get the divided by 2 when dividing 42 and 2 idk this

[mbrandl11]

@Alexiablack101

Since both 42 and 100 are even I know that we can divide them both by two. :-)

[LoouiBfly]

@Alexiablack101 because 2 is the LCD or lowest common denominator for both 42 and 100

[OverLoadVEVO]

Why Would Yuo Use NiNE i dont get it

[mbrandl11]

@OverLoadVEVO

A fraction with nine as the denominator gives us the single repeating decimal.

[GodBlessed22]

this is like school

[MRcoolkidx45]

so if it was 0.68 would it be 68 over 100 and would it be the same thing? (68 over 100)

[mbrandl11]

@MRcoolkidx45

Exactly! Then we can simplify 68/100 from there.

[Gabriel922722]

ho do you write so good with you mouse :D

[mbrandl11]

@Gabriel922722

I use a USB tablet to write in the videos. My mouse writing skills aren't that good! :-)

[gardheere23]

WHICH SOFTWARE DID YOU USE..PLEASE REPLY...

[mbrandl11]

@gardheere23

For this video, I used the free CamStudio to record and Paint.NET as my "whiteboard".

Both are free and easy to use! Let me know if you have any other questions! :-)

[2cute402]

i understood all of that tnxs soo helpfull :D

[zavost]

8 people hate math or flunked their test.

[MAVzzMAN]

Hey dude sweet video, i learned alot from this. The only but i was confused on was that 0.333333333... part but now i get it. thx for the video :)

[mbrandl11]

@emmanuel5ful

You got it! And that simplifies to 2/3 of course! :-)

[PeaceLove286]

THANK YOU SOOOOOOOOO MUCH ! U r really GOOD AT MATH :D

[mbrandl11]

@emmanuel5ful

Because to write any single repeating digit as a fraction we put it over 9. Try dividing 1 by 9, 2 by 9, 3 by 9, etc to see that it's true. Then sometimes we can simplify like in the case of 3/9 and 6/9. :-)

[doubleRRify]

This was very helpful,Thanks.

[Cozmiphonic]

Try "Fraction Simplifier!" on Android market for this. It helps a lot!

[jmer2508]

Thnx thay helped a lot gotta take asvab soon nd tryna study to pass....anyone who can help I would appreciate it. -J-

[howardsrollin]

Thanks dude, gotta take the ASVAB soon, this helps tons, great vid.

[HoodieNinjaMe101]

Thank you! I forgot all that, but now I know how again thanks!

[mbrandl11]

@ZacksTech

Right on! Good work!

[PatmansRemixxx]

Thank you for making this, I'm tutoring a little boy and I forgot all of this stuff haha

[hakar1]

nice explanation but 25/25 = 1 not 3



[mbrandl11]

@hakar1

You're right. 25/25 is one, which is what was used to simplify. The three comes from 75/25 = 3 and four comes from 100/25.

:-)

[12minecraftdude]

you da man

[munkimadness]

being addicted to scientific calculators makes you forget important things :(

[DarkAshes27]

you explain very well but you never explained how you get the numbers you divide it with to simplify

[mbrandl11]

@DarkAshes27

We can either find the GCF of the numerator and denominator, or we can just divide by any number that both are divisible by until there aren't any more numbers that they're both divisible by other than one.

I hope that helps! :-)

[DarkAshes27]

@mbrandl11 thanks ^_^

[IcePrincess619]

Hmm a new favorite teacher besides "NorthStar15"

[MegaMrpak]

Thanks alot:) very helpfull

[GABRIELBARRETTMMA]

Wow! Thank you for braking it down Wooooooow BIG HELP!! I could not figure out some things and you made it easy.. On problem why turn the 0.3333333... Into 3 over 9??? so 0.66666666 still is 6 over 9 ???

[mbrandl11]

@GABRIELBARRETTMMA

Right on!

Then you can, of course, simplify them into 1/3 and 2/3 respectively.

I'm glad you found the video helpful! :-)

[kamranbek]

What if there are more than 1 digit on the left of the decimal?

But thanks! The rest of the information helped alot! =D

[mbrandl11]

@kamranbek

Anything to the left of the decimal is the whole number if converting into a fraction. If you're converting into a percent, you'd just move the decimal two places to the right. So 34.5 would be 3450%.

I hope that helps! :-)

[kamranbek]

@mbrandl11 IT DID!! =D

Omg ur so smart! XD

Dude what if the awnser needs to be 100% or less? >.~

[mbrandl11]

@kamranbek

Can you give an example? I'm not sure what you mean.

[Substantial666Riot]

THANK YOU SO MUCH!!!!

after a few all nighters of studying, im very confident about tomorrows test. very well explained lesson! cheers!

[arhamomar]

thnx

u r amazxin! :D

[CheetahTira1412]

THANK YOU MAN you helped alot! :)

[juanlmesl]

THANKYOU

[Lipzofanangel257]

THANKYOU im in 8th grade and i swear to gosh sometimes during math i thought i was in spanish :/. I'm a dumb blonde and this really helped! that sure does say something!

[Thenerdynerd1]

Wow YouTube has everything I never thought I will find this

[ABC129090]

You saved me dude

[thelittlejennie]

thaaaaaank youuuuu!!!!!!!!!!!!!!!!



[Megaultraawesome99]

not gonna lie,im in fifth grade accelerated math,and you REALLY saved me here. thanks :D

[sungod1019]

THis math is the easy part. It gets a Thousand times harder. Algebra, Geometry , Calculus :( ahhhhhhhhhhh!!!!!!

[fastlanete23te]

Thank you so much for this video, its been very helpful. I've got a maths exam tomorrow and didn't feel confident doing fractions and decimals but I do now thanks to you.

[dpatterson007]

The was a great review thanks for posting it!

[ActressAngie]

Thanks! This helped me tremendously. I am currently refreshing my brain for the CBEST and now I am remembering how much I loved math in school while learning it!! :)

[DOMINICKTHEHAMSTER]

41 divided by 2 isnt 21, The correst answer is 20 1/2

[mbrandl11]

@DOMINICKTHEHAMSTER

You're right. Where am I dividing 41 by 2 though?

[DOMINICKTHEHAMSTER]

@mbrandl11

When you're changing the decimal into the fraction, you divided 42/100 by 2.

[mbrandl11]

@DOMINICKTHEHAMSTER

You got it!

42/2 = 21

;-)

[sammohung82]

iv been redoing maths gcse and i have had so many other ways to work it out and spent ages trying what one works best for me .. and in less than 3 min u made it SOO CLEAR ... THANK YOU

[Fatima2716]

WOW! thats helped me SOO MUCH... THANX

[lastcast960]

San q ^_^

[noWatimsayin1]

how about something like 6.016? how would you convert this? thank you

[mbrandl11]

@noWatimsayin1

Three decimal places would be the thousandths. So we put the decimal part over 1000 and simplify:

016/1000 or 16/1000

Divide by 8 on the top and bottom to get:

2/125

Finally, bring back the six for an answer of:

6 2/125

I hope that helps! :-)

[noWatimsayin1]

@mbrandl11 That does help, thank you very much man.

[BeerCanBeachKitty]

cool, it helped me:D and my volume was down and it hurt my ears a LITTLE not to much:( great job though:D

[Euphoria4u2c]

Hey! I appreciate the video for it's simplicity. You're a better teacher than my math teacher! I guess he assumes that we all ready know how to do these conversions after giving us questions. This is the third time I've had to sub come (spelling correction?) to using the net to learn what the teacher should be explaining. Highly appreciated!

[pathello1]

wow the lat problem was actually in my homework yay!

[AnaTipton]

How did you get the 9 in .3333333 ,although the answer is correct ,where did 9 in get in there?

[mbrandl11]

@AnaTipton

Anytime you have a single repeating digit, you put it over 9 to make a fraction. So, for example, 0.222222... would be 2/9. 0.5555555.... would be 5/9. Divide the fractions out to double-check and find those decimals. :-)

I hope that helps!

[beachandsunandsand]

Thank you soooo much for your help. You helped my son out. And he says "yeahhhhh" !!!! :)

[rbroatea]

thank u

[sexysusan2010]

yes it was very helpful!!! thank you.

[kimchi4fun]

Thank you :D

Way better than that lady with the monotone voice o___O"

[genjosanzo1988]

Man, all of your videos are helpful. I'm self-studying right now for my entrance exam. And I suck at math. Every time I'm in trouble, I'm always looking for your videos. Thank you so much for this. You're really great

[nightshadecat]

Thanks that is so much easier then the way my teacher explained it in class! technology is wonderful!

[thewarri]

thx i forgot how to do this

[xXSorrowxPainXx]

What if u have two repeating numbers?

[mbrandl11]

@xXSorrowxPainXx

Do you mean something like this: 0.32323232...

We would put the two repeating digits over 99, so the above decimal would be 32/99.

The same is true for three repeating decimals, put them over 999, and so on.

I hope that helps! :-)

[free2waait]

YOU ARE AWESOME! you teaching style is very likable, doesnt piss me off NICE ONE!
