Answer 1

Given :- Colin’s piano lesson is 45 minutes, or Three-fourths of an hour, long. If he practices 6 different songs and spends an equal amount of time on each song, what fraction of an hour does he spend practicing each song ?

A.1/12

B.1/8

C.2/9

D.9/2

Solution :-

we have,

→ Colin’s piano lesson is = 45 minutes .

and,

→ he practices total different songs = 6

also, given that, he spends an equal amount of time on each song .

So,

→ Time he spend on each song = Total time of lesson / Total number of songs he practice = 45/6 = (15/2) Minutes.

now, we know that,

→ 60 minutes = 1 hour .

→ 1 minute = (1/60) hour .

then,

→ (15/2) minutes = (1/60) * (15/2) = (1/8) hours. (Option B) (Ans.)

Hence, (1/8) fraction of an hour does he spend practicing each song .
