To find out what percentage 12 is of 30, you can use the following formula:
**Percentage = (Part / Whole) × 100**
Here, the ‘Part’ is 12, and the ‘Whole’ is 30. Plugging these values into the formula:
**Percentage = (12 / 30) × 100**
First, divide 12 by 30:
**12 ÷ 30 = 0.4**
Next, multiply the result by 100 to get the percentage:
**0.4 × 100 = 40%**
So, 12 is **40%** of 30.
