15 is 25% of 60.

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

15/60 = 25/100

Solution:

we have been asked to find

15 is what percentage of 60.

Let 15 is x% of 60.

Then we can write

[tex] 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\\ [/tex]

Hence 15 is 25% of 60.
