I'd do it by saying 10% of 82. is 8.2 (that's move decimal point to the left one place)

Now multiple 8.2 by 2 (double it).

Answer 16.4.

Note: Decimal point though not displayed in the 82 comes after the 2.

i like the guy who presented the video.  He is cute... i would love to have him to be my teacher everyday...

Im trying to figure out something almost the same but you sort it different like 90 is 30% of what

[HUNTERimp1]

if i get lets say 33 of 40 on a test, i first multiply 33 by 100 then divide it by 40, and the results should come.

@N30NN4ILP0LISH Huh? If you think I'm upset then clearly you're not understanding my posts. I've simply told you that the creator changed the video after my first comment, since, as my first comment pointed out, the version he had originally was not only aesthetically challenged but rendered the images useless. But, make sure to learn solid math skills. It's very important, even though most people somehow think it's hard and/or boring. Very useful later in life.

@cvg1099 Obviously you're upset b/c I was kinda getting the POINT of the vid. And why did you even watch?

[cvg1099]

@N30NN4ILP0LISH Actually, the creator of the video just recently re-positioned the text boxes to the bottom of the screen after he read my comment. What was there originally was one huge box of text covering literally the entire screen, rendering the image of a person standing at a chalkboard completely useless. But, as long as we're talking about discovering things on one's own, maybe you need to spend some time discovering how bad you look when you resort to childish name-calling.

good job sir.

[cvg1099]

And the point of filming a human in front of a chalkboard in this video IZZZZZ......?
