Question: how would you find the percent of 33 1/3 out of 90 by using fraction settup!I can do whole numbers but not mixed. This is how to do whole numbers say it was 33 of 90

33 x 90 = 2970
100 x 1 = 100
2970 divided by 100
the answer is 29.7

so how do you do it with a mixed number

Hi Julie,

To work with the mixed number 33 1/3 I would first express it as a fraction.

33 1/3 = 33 + 1/3 = 99/3 + 1/3 = (99 + 1)/3 = 100/3

Now repeat the process you used for 33, but using 33 1/3 written 100/3. That is

33 1/3 x 90 = 100/3 x 90 = 3000

and continue.

Cheers,
Penny
