You did not show how 20 divided by 15 leaves you

1 and one half witch is the lowest number

Hi. The final fraction was actually 22/15. If you wanted to convert this into a mixed number, it would be 1 and 7/15. This answer would also be correct.

im confused on the multiplication part...do you just multiply the denominators by each fraction? like 1/2 and 1/3 do you multiply 3 by 1/3 and 2 by 1/3?

22/15 = 1 and 7/15

You stated on the video that 22 over 15 can not fall as a lower number this is not true it can be worked out to a lower # 15/22 = 1 then 15 X 1

witch in turn would leave you 1 and 1 15th that would be the lowest # if you had to work it out but you new this but did not add it to the video this information is the key to the lowest #
