Answer Attempt 1 out of 2

Answer 1

To find 15% of a number, set up a proportion using known percentages and solve for the unknown number.

Step-by-step explanation:

To find 15% of the number, we can use proportions. Let's assume the number is 'x'. We know that 25% of x is 65, so we can write this as (25/100)x = 65. Solving for x, we find that x = 65 * 100 / 25 = 260.

Now, we need to find 15% of 260. We can set up another proportion: (15/100)x = ?% of 260. Rearranging the equation, we have (15/100)x = (15/100) * 260 = 39.

Therefore, 15% of the number is 39.
