160 is what percent of 40? Please explain. The Correct Answer and Explanation is: To determine what percent 160 is of 40, use the following formula: Percentage=(PartWhole)×100\text{Percentage} = \left( \frac{\text{Part}}{\text{Whole}} \right) \times 100Percentage=(WholePart​)×100 In this case, the part is 160 and the whole is 40: Percentage=(16040)×100=4×100=400%\text{Percentage} = \left( \frac{160}{40} \right) \times 100 = 4 \times
