\(\frac{72}{45} \times 100\%=\frac{8 \times 9}{5 \times 9} \times 100\%=\frac{8}{5} \times 100\%=8 \times 20\%=\boxed{160\%}\)

72 is 160% of 45.

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
