Question

What percent of 45 is 72?

Answer 1

`(72)/(45) * 100\%=(8 * 9)/(5 * 9) * 100\%=(8)/(5) * 100\%=8 * 20\%=\boxed{160\%}`

72 is 160% of 45.

Answer 2

I would set up an equation. Percentages are parts of a whole, and you are trying to find the percentage. So set it up like this... keep in mind "of" means multiply.
`45x=72` Divide both sides by 45.
`x=1.6` So move the decimal places two spaces to the left, and that leaves your answer to be 160% of 45 is 72
