Answer: see below
Step-by-step explanation:
When multiplying or dividing, use the smallest number of significant figures (sf) of the digits provided.
37(a) 24 × 3.26 = 78.24 2 sf × 3 sf --> round to 2 sf's
≈ 78
(b) 120 × 0.10 = 12 2 sf × 2 sf --> round to 2 sf's
= 12
(c) 1.23 × 2.0 = 2.46 3 sf × 2 sf --> round to 2 sf's
= 2.5
(d) 53 × 1.53 = 81.09 2 sf × 3 sf --> round to 2 sf's
= 81
38(a) 4.84 ÷ 2.4 = 2.0167 3 sf × 2 sf --> round to 2 sf's
= 2.0
(b) 60.2 ÷ 20.1 = 2.995 3 sf × 3 sf --> round to 3 sf's
= 3.00
(c) 102.4 ÷ 51.2 = 2 4 sf × 3 sf --> round to 3 sf's
= 2.00
(d) 168 ÷ 58 = 2.896 3 sf × 2 sf --> round to 2 sf's
= 2.9
