Mathematics Questions and Answers

PART A
Question 1:
I.
a) 750 ÷ (4 2 + 3 2) (4 × 2 + 4)
= 700 ÷ (25) (12)
= 700 ÷ 300
= 2.33
b) (900 ÷ 152) (220 ÷ 11)
= (4) (20)
= 80
c) 480 ÷ 6 (3 + 2 × 2) – 215
= 480 ÷ 6 × 7 – 215
= 480 × 1/42 – 215
= 11.43 - 215
= -203.57
d) 2 × [452 ÷ (10 × 34)]
= 2 × [2025÷ 810]
= 2 × 2.5
= 5
e) [200 ÷ (6 + 4)] ÷ 2 + 15 – 8 + [(22× 2) 2]
= [200 ÷ 10] ÷ 9 + 16
= 20 ÷ 25
= 0.8
= 112
II.
a) 260
b) 64
c) -17
