Find the percent. Round to the nearest whole percent.

Question

159 people in favor out of 350 people surveyed.

Answer 1

Percent is a fraction multiplied by 100%.
The fraction is 159/350=0.4543
Multiply by 100% to get 45.43%
The question requires the nearest whole percent. So you'd have to choose between 45% or 46%, whichever is closer to 45.43%.
