Answer:
16/75 = .2133 or 21.33%
23/90 = .255 or 25.55%
13/15 = .866 or 86.66%
11/90 = .122 or 12.22%
Explanation:
We know that to find the percent of a number you must multiply the percent by the number like this:
23% of 60
.23 x 60 = 13.8
Now to go backwards all you have to do is divide back. So for instance if we wanted to find now what percent 13.8 is of 60, we would divide 13.8/60 and get .23.
So for these just divide all the first numbers by the second numbers:
16/75 = .2133 or 21.33%
23/90 = .255 or 25.55%
13/15 = .866 or 86.66%
11/90 = .122 or 12.22%
hope this helps!
