Q.4 Write five pairs of integers (a, b) such that a ÷ b = -3. One such pair is (6, -2) because 6 + (-2) = -3.

(i) (15, -5) Because, 15 ÷ (–5) = (–3)
(ii) (-15, 5) Because, (-15) ÷ (5) = (–3)
(iii) (18, -6) Because, 18 ÷ (–6) = (–3)
(iv) (-18, 6) Because, (-18) ÷ 6 = (–3)
(v) (21, -7) Because, 21 ÷ (–7) = (–3)
