To find out what percentage 15 is of 20, you can use the following formula:
**Percentage = (Part / Whole) × 100**
In this case, the ‘Part’ is 15 and the ‘Whole’ is 20. Plugging these values into the formula:
**Percentage = (15 / 20) × 100**
First, divide 15 by 20:
**15 ÷ 20 = 0.75**
Then, multiply the result by 100 to get the percentage:
**0.75 × 100 = 75%**
So, 15 is **75%** of 20.
