Question

If you have to represent 7 hours and 15 minutes in hours as decimals, how would you do it?

• A. 7.5 hours
• B. 7.15 hours
• C. 7.25 hours
• D. 7.3 hours

Answer 1

The correct option is C 7.25 hours

60 minutes = 1 hour

1 minute = $\frac{1}{60}$ hour

15 minutes = 15 × $\frac{1}{60}$
= $\frac{15}{60}$
= 0.25 hours

So, 7 hours and 15 minutes $=(7+0.25)=7.25$ hours
