Question

4) Verify the following
i) (3/4+-2/5) +-7/10=3/4+(-2/5+-7/10)​

Answer 1

Answer:

LHS = RHS

For LHS

LCM = 20

= 3/4 = 15/20 & -2/5 = -8/20

= 7/20 -7/10

LCM = 20

= 7/20 -14/20 = -7/20

For RHS

LCM = 10

-2/5 = -4/10

= -4/10 -7/10 = -11/10

LCM = 20

3/4 = 15/20

-11/10 = -22/20

= 15/20 -22/20 = -7/20

Hence Verified
