Portion is found by _____ the rate times the base
To find the portion, you need to multiply the rate by the base. The rate represents the percentage or fraction of the base that you want to find.
Here's an example to illustrate the process:
Let's say you want to find 40% of a number, which is the rate, and the number itself is the base. To find the portion, you would multiply 40% (or 0.40 as a decimal) by the base.
For example, if the base is 100, you would calculate 0.40 * 100 = 40. Therefore, 40 is 40% of 100.
