we have been asked to find

15 is what percentage of 60.

Let 15 is x% of 60.

Then we can write

$60*x \ percentage=15\\ \\ 60*\frac{x}{100}=15\\ \\ \text{Apply the concept of cross Multiplication we get}\\ \\ 60x=1500\\ \\ x=\frac{1500}{60}\\ \\ x=\frac{150}{6}\\ \\ x=25$

Hence 15 is 25% of 60.

Answer 2

15 is 25% of 60.

15/60 = x/100
15 times 100 = 60 times x
1500/60 = 25

15/60 = 25/100
