Question

Verify that a ÷ (b + c) ≠ (a ÷ b) + (a ÷ c) for the following values of a, b and c.

a = (−10), b = 1, c = 1

Answer 1

a = −10, b = 1, c = 1

L.H.S  = a ÷ (b + c)

= (−10) ÷ (1 + 1)

= (−10) ÷ 2

= −5

R.H.S = (a ÷ b) + (a ÷ c)

= [(−10) ÷ 1] + [(−10) ÷ 1]

= −10 − 10

= −20

Hence, a ÷ (b + c) ≠ (a ÷ b) + (a ÷ c)
