Answer 1

Answer:

Option (c) is correct.

Expression $7\frac{1}{5}-6\frac{2}{5}$ simplified to $\frac{4}{5}$

Step-by-step explanation:

 Given : expression $7\frac{1}{5}-6\frac{2}{5}$

We have to find the value of the given expression  $7\frac{1}{5}-6\frac{2}{5}$

Consider the given expression  $7\frac{1}{5}-6\frac{2}{5}$

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

and  $6\frac{2}{5}=\frac{32}{5}$

Thus,  $7\frac{1}{5}-6\frac{2}{5}$ becomes

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

LCM (5,5) = 1

Thus,  $\frac{36}{5}-\frac{32}{5}=\frac{36-32}{5}=\frac{4}{5}$

Thus,  Expression $7\frac{1}{5}-6\frac{2}{5}$ simplified to $\frac{4}{5}$

Answer 2

7 1/5 - 6 2/5

36/5 - 32/5 = 4/5
