Taking x = -4/9, y = 5/12 and z = 7/18, find: the rational number which when multiplied by y to get x.

Solution:

It is given that

x = -4/9, y = 5/12 and z = 7/18

If A is multiplied by y, we get x

A × y = x

Substituting the values

A × 5/12 = -4/9

We can write it as

A = -4/9 × 12/5

A = -48/45

Therefore, the rational number which when multiplied by y to get x is -48/45.
