Question

7 1⁄5 – 6 2⁄5 = ?

A. 4⁄5
B. 1 4⁄5
C. 1 1⁄5
D. 13 3⁄5

Answer 1

A

Explanation:

Change the mixed numbers to improper fractions

7
`(1)/(5)` =
`(36)/(5)`

6
`(2)/(5)` =
`(32)/(5)`

The subtraction is then

`(36)/(5)` -
`(32)/(5)`

Both fractions have a common denominator so subtract the numerators leaving the denominator

=
`(36-32)/(5)` =
`(4)/(5)` → A
