Answer 1

C

Explanation:

To solve it will be easier to turn 7 into a rational number with the same denominator as 5/7

To do this make ratios

`(7)/(1)=(x)/(7)`

Now solve for x

x = 49

This means that the fraction will be 49/7

`(49)/(7)-(5)/(7)=(44)/(7)`

This can also be written as
`6(2)/(7)`
