4vir4ik [10]

Answer:

2/3 of band practice was spent playing music.

Step-by-step explanation:

First find the common denominator.

6 times 4 is 24

8 times 3 is 24

multiply the numerators by the same value as the denominator (for 1/8 both the 1 and the 8 would be multiplied by 3, and for 1/6 both the 1 and the six would be multiplied by 4)

4/24  +  3/24

next the questions is asking for the remaining practice time.

add numerators when the denominators are the same.

4  +  3  =  7

=  7/24

24/24  -  7/24  =  16/24

(24  -  7  =  16)

now divide both the numerator and denominator by the same number.

16  ÷  8  =  2

24  ÷  8  =  3

The answer would be that 2/3 of band practice was spent playing music.
