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 x

28x = 500

x = 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.

5% means 0.05. "Of" means "times".

0.05 x 2.8 = 0.14
