Answer 2

Step-by-step explanation: Ques 1

1.  -5/7 + 3/7=$\frac{-5+3}{7} = \frac{-2}{7}$

2.  -15/4 + 7/4=$\frac{-15+7}{4} = \frac{-8}{4} = -2$

3. 5/7 + 9/11=$\frac{55+63}{77} = \frac{118}{77}$

Ques2

1. 3/4 - 1/4=$\frac{3-1}{4} = \frac{2}{4}=\frac{1}{2}$

2. 7/11 - 3/7= $\frac{49-33}{77} = \frac{16}{77}$

3.  6/10 - 11/20​= $\frac{12-11}{20} = \frac{1}{20}$
