Question

450 is 75.2 percent of what number with solution

Answer 1

approximately 598.4

Explanation:

Instead of trying to remember when to multiply and when to divide to solve percent problems, I use the following proportion:

`(`

450 is = "is", 75.2 = percent of what number = "of" (unknown), so

`(` becomes
`(450)/(x) =(75.2)/(100)`.

Solve the proportion:

`(450)/(x) =(75.2)/(100)`
450(100) = 75.2x
45000 = 75.2x
45000/75.2 = x
x ≈ 598.4
