Answer:

OK I will answer your doubt

STEP BY STEP EXPLANATION

1. -4/3 and 3/7

LHS = -4/3 + 3/7

= LCM of 3,7 = 21

= -4/3 × 7/7 = -28/21

= 3/7 × 3/3 = 9/21

= -28 +9/21 = -19/21

RHS = 3/7 + -4/3

= LCM of 7,3 = 21

= 3/7 × 3/3 = 9/21

= -4/3 × 7/7 = -28/21

= +9 -28/21 = -19/21

LHS=RHS

2. -2/-5 and 1/3

LHS = -2/-5 + 1/3

= LCM of -5,3 = 15

= -2/-5 × 3/3 = -6/-15

= 1/3 × 5/5 = 5/15

= -6 +5/-15 = -1/-15 = 1/15

RHS = 1/3 + -2/-5

= LCM of 3,-5 = 15

= 1/3 × 5/5 = 5/15

= -2/-5 × 3/3 = -6/-15

= +5 -6/-15 = -1/-15 = 1/15

LHS = RHS

3. 9/11 and 2/13

LHS = 9/11 + 2/13

= LCM of 11,13 = 143

= 9/11 × 13/13 = 117/143

= 2/13 × 11/11 = 22/143

= 117 + 22/143 = 139/143

RHS = 2/13 + 9/11

= LCM of 13,11 = 143

= 2/13 × 11/11 = 22/143

= 9/11 × 13/13 = 117/143

= 22 + 117/143 = 139/143

LHS = RHS
