Chapter 2, Problem 5PP

Grade point average (GPA) in a 4-point scale is calculated by using the following formula:

$\text{GPA}=\left(\frac{\text{Percentage}}{100}\right)\times 4$

Write a program that takes as input the percentage from a user. The program should then output the user's GPA on the screen. The format of the output should be as follows, assuming the user's percentage is 85:

$\left(85/100\right)*4=3$
