e.24/10​

Answer 1

Answer:

Both answers C & E are correct

Step-by-step explanation:

$\sf\frac{7}{10}-\frac{4}{40}$

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.

$\sf\frac{7*4}{10*4}-\frac{4}{40}\\\\\sf\frac{28}{40}-\frac{4}{40}\\\\\sf\frac{28-4}{40}\\\\\sf\frac{24}{40}$

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

$\sf\frac{3}{5}$

Therefore, the answer is $\sf\frac{24}{40}$ = $\sf\frac{3}{5}$
