Three eights of the cast in a musical have to sing. What fraction of the cost does not have to sing?
(8/8) - (3/8) = 5/8
I got 6/16 because 3x2 equals 6 and 8x2 equals 16
Well you have to do is 2x3= and then do the same thing with 8 2x8=.

My answer is 3/8 because 3/8 is a halve and 3/8+3/8=6/8 and 6/8 is also a halve
To find the fraction of the cast that does not have to sing in the musical, we first need to determine the fraction of the cast that does have to sing.
We are given that three eighths (3/8) of the cast has to sing.
To find the fraction that does not have to sing, we subtract the fraction that does have to sing from the total fraction representing the cast.
The total fraction representing the cast is 1, because the entire cast is being considered.
So, to find the fraction that does not have to sing, we subtract 3/8 from 1:
1 - 3/8 = (8/8) - (3/8) = 5/8
Therefore, 5/8 of the cast does not have to sing.
To summarize, the fraction of the cast that does not have to sing is 5/8.
