Answer:

Mark me as brainlist

Step-by-step explanation:

a-b=3/5-(-7/5)=3/5+7+5=10/5=2

b-a=-7/5-3/5=-10/5=-2

so a-b is not equal to b-a

Answer 2

$a - b \\ = \frac{3}{5} - \frac{ - 7}{5} \\ = \frac{3 + 7}{5} \\ = \frac{10}{5} \\ = 2$

$b - a \\ = \frac{ - 7}{5} - \frac{3}{5} \\ = \frac{ - 7 - 3}{5} \\ = \frac{ - 10}{5} \\ = - 2$

Hence ,

a-b not equals b-a
