Question

James started taking piano lessons. He had to practice$\frac{13}{15}$
hrs a day. If he stops after 15 days how many hrs did he practice?​

Answer 1

Answer:

13 hrs

Step-by-step explanation:

Time practised in 1 day = 13/15 hrs.

Time practised in 15 days = 13/15 x 15

                                           = 13 hrs

Answer 2

Answer:

312 hours

Step-by-step explanation:

By Unitary method, $\frac{13}{15} \, hours \, a \, day \times 24 \ = \frac{312}{15} hours \, per \, day$

So in 15 days that is $\frac{312}{15} \times {15}$ = 312 hours
