Question

The product of two rational number is -7. If one of the number is -8/11 , find the other.

Answer 1

-8/11×a=-7

a= -7×-11/8

a=77/8

Answer 2

Solution:

Let m,n are two rational numbers.

m = -8/11 ,

and

m × n = -7 [ given ]

=> (-8/11) × n = -7

=> n = (-7)×(-11/8)

=> n = 77/8

Therefore,

The other number (n) = 77/8
