What percentage of 5/2 hours is 15 minutes?

elena-14-01-66 [18.8K]

Answer:

10 %

Step-by-step explanation:

15 mn = 1/4 h

We have :

$\frac{\frac{1}{4} }{\frac{5}{2} } =\frac{1}{4} \times \frac{2}{5} =\frac{2}{20} =\frac{1}{10}=0.1$

Then the percentage that 15 mn represents of 5/2 h is :

0.1 × 100 = 10 %
