In my opinion, I like using improper fractions, but that's up to you:
7 1/5 = 36/5
6 2/5 = 32/5
36/5 - 32/5 = 4/5
Answer:
[tex]=\frac{4}{5}[/tex]
Step-by-step explanation:
[tex]7\frac{1}{5} - 6\frac{2}{5}[/tex]
[tex]=\frac{36}{5} - \frac{32}{5}[/tex]
[tex]=\frac{36-32}{5}[/tex]
[tex]=\frac{4}{5}[/tex]
