What percent of 30 is 15?

15/30 * 100 = 50%

50%

15/30 reduced is 1/2

To find the percentage of one number in relation to another number, we can use the following formula:

Percentage = (Part / Whole) * 100

In this case, the "whole" is 30 and the "part" is 15. Plugging the values into the formula, we get:

Percentage = (15 / 30) * 100

Simplifying the expression, we have:

Percentage = 0.5 * 100

Therefore, the answer is 50%.

So, to find the percentage, divide the given number by the total number and then multiply by 100.

In the case of 15 out of 30, we get (15/30) * 100 = 0.5 * 100 = 50%.
