100

Percent correct expresses a rate per hundred. After dividing correct responses by total opportunities, you have a proportion between 0 and 1. To express that as a percent, multiply by 100. For example, 15 correct out of 60 opportunities is 15/60 = 0.25; times 100 equals 25%. So the value you multiply by is 100.
