Base is found by __________ the portion by the rate

To find the base, you need to divide the portion by the rate. Here's the step-by-step process:

1. Write down the given values: the portion and the rate.
2. Divide the portion by the rate.
3. The quotient obtained from the division is the base.

Let's illustrate this with an example:

Example: The portion is 40 and the rate is 0.2. Find the base.

1. Given values: portion = 40, rate = 0.2.
2. Divide the portion by the rate: 40 ÷ 0.2 = 200.
3. The base is 200.

Therefore, by dividing the portion by the rate, we obtained the base of 200.
