Verified answer

(x/100)(55) = 15.4

55x / 100 = 15.4

55x = 1540

x = 28

check: 55 x .28 = 15.4

u do 15.4 and divide it by 55 and it will give u a decimal times that by 100 and that should give u 28 being the answer

15.4 / 55 * 100 = 28%

"'x' is what percent of 'y'?" always gives the same ratio.

x / y = % you want / 100%

15.4 / 55 = x% / 100%

This is the ratio you need to use. I am sure you can solve it from here. It is your homework, and you'll need practice to get ready for test day.

15.4 / 55 x 100

= 28%

its not hard , in simple terms xD hope i helped

15.4/100 = x/55

x = 8.47
