Question

By what rational number should -11/12 be multiplied to get the product -11/20.

Answer 1

-11 / 12 × a = -11/20.

=> a = -11/20 ÷ -11/12

=> a = -11/20 × -12/11

=> a = -1/20 × -12/1

=> a = [(-1) × (-3)] / 5

=> a = 3/5

Therefore , -11/12 should be multiplied with 3/5 to get -11/20

Answer 2

(-11/12) * x = -11/20
x= -11/20 / -11/12
x= 3/5
