Answer:
A
Step-by-step explanation:
Change the mixed numbers to improper fractions
7 [tex]\frac{1}{5}[/tex] = [tex]\frac{36}{5}[/tex]
6 [tex]\frac{2}{5}[/tex] = [tex]\frac{32}{5}[/tex]
The subtraction is then
[tex]\frac{36}{5}[/tex] - [tex]\frac{32}{5}[/tex]
Both fractions have a common denominator so subtract the numerators leaving the denominator
= [tex]\frac{36-32}{5}[/tex] = [tex]\frac{4}{5}[/tex] → A
