Question

Represent 12 hours and 45 minutes as a decimal.

• A. 12.75 hours
• B. 11.53 hours
• C. 12.55 hours
• D. 12.45 hours

Answer 1

The correct option is A

12.75 hours

60 minutes = 1 hour

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

45 minutes = $45\times \frac{1}{60}$ = 0.75 hour

So, 12 hours and 45 minutes = (12 + 0.75) = 12.75 hours
