As soon as you form a percent sign (%) after a number, the percent number format will it is in be applied to that cell **automatically**.

As you might remember from math class, a portion can additionally be composed as a **decimal**. Therefore 15% is the exact same thing together 0.15, 7.5% is 0.075, 20% is 0.20, 55% is 0.55, and also so on.
