Answer:

Both answers C & E are correct

Explanation:


\sf(7)/(10)-(4)/(40)

First, make the denominator the same to solve the fraction.

For that, multiply both the numerator and denominator by 4 in the fraction 7/10.


\sf(7*4)/(10*4)-(4)/(40)\\\\\sf(28)/(40)-(4)/(40)\\\\\sf(28-4)/(40)\\\\\sf(24)/(40)

To write the answer in its simplest form divide both the numerator and denominator by 8.


\sf(3)/(5)

Therefore, the answer is
\sf(24)/(40) =
\sf(3)/(5)
