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 ?
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.
hope this helps......
