To convert a ratio to a percentage, you can follow these steps:
Step 1: Add the two numbers in the ratio together. In this case, 2 + 3 = 5.
Step 2: Divide the first number in the ratio by the sum obtained in step 1. So, 2 ÷ 5 = 0.4.
Step 3: Multiply the result from step 2 by 100 to get the percentage. Thus, 0.4 × 100 = 40.
Therefore, the ratio 2:3 can be converted to 40%.
