Ther school and found that .55 of the students she surveyed said their favorite class is math . another 15% of the students she surveyed reported that their favorite class is science. how many more students in the survey prefer math over science

Well .55 as a percent is 55% straight. Then you would have to do 55% - 15% to see the difference then, that difference will be your answer. My preferred steps:

55% - 15%

55 - 15 = 40

So this means 40% of the students surveyed math over science.

divide 48 by 4 to obtain one part of the ratio

= 12 ← 1 part of the ratio

3 parts = 3 × 12 = 36 ← number of girls
