Taking x = -4/9, y = 5/12 and z = 7/18, find: (x ÷ y) × z

Solution:

It is given that

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

We know that

(x ÷ y) × z = (-4/9 ÷ 5/12) × 7/18

Reciprocal of 5/12 is 12/5

= (-4/9 × 12/5) × 7/18

It can be written as

= (-4 × 12 × 7)/ (9 × 5 × 18)

= -56/135

Therefore, (x ÷ y) × z is -56/135.
