Question

A bag contains A markers, 3/8 of which are red. How many other color markers are in the bag?

Answer 1

8 is the total number of markers in the bag. There are 3 out of 8 that are red. 8-3=5 so there are 5 out of 8 markers that are not red and that are other colors - or 5/8 are other colors.

Answer 2

`(5A)/(8)` are the other color markers in the bag.

Explanation:

A bag contains A markers,
`(3)/(8)` of which are red.

Number of red markers =
`(3)/(8)` of A

=
`(3A)/(8)`

Now number of other color markers in the bag = Total markers - number of red markers

Number of other markers = A -
`(3A)/(8)`

=
`(8A-3A)/(8)`

=
`(5A)/(8)`

therefore,
`(5A)/(8)` are the other color markers in the bag.
