What does percent mean in arithmetic?

Explanation:
Percent expresses a number as a fraction of 100. That means to use a percent in arithmetic, you convert it to a decimal by dividing by 100. For example, 25% equals 25/100 = 0.25. So dividing by 100 is the operation that matches what percent means. Multiplying by 100 would turn a decimal into a percent, not describe the meaning of percent itself, and adding 100 or subtracting 1 aren’t related to how percent expresses a part of a hundred.
