Find the product of -2 3/4 and 5 6/7.

Solution:

Given, the numbers are -2 3/4 and 5 6/7

We have to find the product of the given numbers

2 3/4 = [2(4) + 3]/4

= (8 + 3)/4

= 11/4

5 6/7 = [5(7) + 6]/7

= (35 + 6)/7

= 41/7

Product of -2 3/4 and 5 6/7 = -11/4 × 41/7

= (-11 × 41)/(4 × 7)

= -451/28

Therefore, the required product is -451/28
