This can be done at least 2 ways.Soln 1: The saying: IS over OF equals PERCENT over 100, tells how to set up a proportion to solve.5/28 = x/100 ... cross multiply and solve for x28x = 500x = 17.86%Soln 2: Translate the word problem into an equation. IS means equals, OF means to multiply.x (28) = 5 solve, get a decimal answer and convert it to a percent.x = 5/28 = 0.1786 = 17.86%Pick which method you like best to use.

m / 3/4 = 28 is the same as m = 3/4 x 28 = 21
Divide 28 by 4. X = 7
Does it say solve for y?
x=28
Set up the equation and solve for z: 28 + z = 56 (next, subtract 28 from each side of the equaition to solve) z = 28
You want an equivalent fraction for 7/28 where the denominator is 100. that is 7/28 = x/100 This will solve to x = 25
