Question

7 1⁄5 – 6 2⁄5 = ? A. 4⁄5 B. 1 4⁄5 C. 1 1⁄5 D. 13 3⁄5

Answer 1

Answer:

A

Step-by-step explanation:

Change the mixed numbers to improper fractions

7 $\frac{1}{5}$ = $\frac{36}{5}$

6 $\frac{2}{5}$ = $\frac{32}{5}$

The subtraction is then

$\frac{36}{5}$ - $\frac{32}{5}$

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

= $\frac{36-32}{5}$ = $\frac{4}{5}$ → A
