Question

Reshma studies for 4 hours and 48 minutes a day. Represent the fraction of the day she spends studying in decimal format.

• A. 4.48
• B. 4.8
• C. 0.2
• D. 0.8

Answer 1

The correct option is C 0.2

Duration spent in studying = 4 hrs 48 mins
= 4 hrs + $\frac{48}{60}\mathrm{hrs}$
= 4 hrs + $\frac{8}{10}\mathrm{hrs}$
=4.8 hrs

Total hours a day = 24
Fraction of the day spent in studying = $\frac{4.8}{24}=\frac{48}{24\times 10}=\frac{2}{10}=0.2$
