Question

Explain how to solve addition and subtraction of rational numbers​

Answer 1

Step-by-step explanation:

1. First we have to make the like rational nos.

2. To make them like,denominators should be same.

3. For same denominators,we have to make the denominators as LCM.

2. then add/subtract the numerators and write the LCM as denominator.

Example-

Add 2/3 and 3/4

2/3 + 3/4

2/3×4/4 + 3/4×3/3(make the denominators as LCM=12)

8/12 + 9/12

(8+9)/12

17/12
