Find the values of: (a) (32 × (−18)) ÷ ((−36)) (b) (32) ÷ ((−36) × (−18)) (c) (25 × (−12)) ÷ ((45) × (−27)) (d) (280 × (−7)) ÷ ((−8) × (−35))
(a)
Answer
16
(b)
Answer
4/81
(c)
Answer
20/81
(d)
Answer
−7
Explanation
(a) 32 × (−18) = −576. (−576) ÷ (−36) = 576 ÷ 36 = 16. (b) (−36) × (−18) = 648. 32 ÷ 648 = 32/648 = 4/81. (c) 25 × (−12) = −300. 45 × (−27) = −1215. (−300) ÷ (−1215) = 300/1215 = 20/81. (d) 280 × (−7) = −1960. (−8) × (−35) = 280. (−1960) ÷ 280 = −7.
