Question

4. Verify the following:

(1) (3/4 + -2/5)+ -7/10 = 3/4 + (-2/5+ -7/10)​

Answer 1

Step-by-step explanation:

3/4-2/5-7/10=3/4-2/5-7/10

15-8-14/20=15-8-14/20

-7/20=-7/20

Answer 2

Answer:

(3/4 + -2/5)+ -7/10 = 3/4 + (-2/5+ -7/10)

(15-8/20)-7/10 = 3/4+(-4 -7/10)

7/20-7/10 = 3/4 - 11/10

14-7/20 = 15-22/20

7/20 = -7/20

LHS is not equal to RHS...
