In a day, robin spends 6 hours at school, sleeps for 9 hours, plays for 3 hours, and spends the rest of the time doing other things. robin spends % of the day playing and % of the day doing things other than sleeping, playing, or going to school.

Robin spends 12.5% of the day playing and 25% of the day doing things other than sleeping, playing, or going to school.

Step-by-step explanation:

In a day, Robin spends his time :

At school = 6 hours

Sleeps = 9 hours

Plays = 3 hours

Total time spent = 6 + 9 + 3 = 18 hours

Time left = 24 - 18 = 6 hours

doing other things = 6 hours

Now we have to calculate what % of the day he is playing and doing other things.

He spends 3 hours in playing = 3 hours of 24 hours

= 3 ÷ 24 × 100 = 12.5%

He spends 6 hours in doing other things = 6 hours of 24 hours

= 6 ÷ 24 × 100 = 25%

Robin spends 12.5% of the day playing and 25% of the day doing things other than sleeping, playing, or going to school.

the answer is b
