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.
