Question

nisha did 5/6 part of an exercise of her math book at same time vishal did 6/7 part of same exercise who has done more and by how much​

Answer 1

Answer:

Vishal has done more work by 1/42

Step-by-step explanation:

Nisha --> 5/6 part of an exercise

Vishal --> 6/7 part of the same exercise

To find the answer, we will first have a common denominator.

LCM= 7 x 6

      = 42

therefore,        Nisha --> 35/42

and,                 Vishal --> 36/42

Clearly, Vishal has done more work and by (36-35)/ 42

                                                                         1/42
