Question

Is this answer is right​

Answer 1

Correct answer is (- 4312/112)

Step-by-step explanation:

We have to check.

Now, (- 4 5/6 + - 7 3/4) × (- 2 3/4 + 5 6/7)

= (- 28/6 - 31/4) × (- 11/4 + 41/7)

= {- (28 × 2) - (31 × 3)}/12 × {- (11 × 7) - (41 × 4)}/28

[ lcm of 6 and 4 is 12 & the lcm of 4 and 7 is 28 ]

= (- 56 - 93)/12 × (- 77 + 164)/28

= (- 149)/12 × 87/28

= - (149 × 29 × 3)/(3 × 4 × 28)

= - (149 × 29)/(4 × 28)

= - 4312/112

This should be the answer.
