700 ÷ 15.1

Answer 1

I'll assume trailing zeros with no decimal point are not significant (e.g. 240 has 2 s.f., 5000 and 700 and 80 have 1 s.f., 750 has 2 s.f.). Answers are rounded according to the usual multiplication/division rules.

1) 0.6 × 72.427 × 240 = 1.04×10^4 → 1×10^4 (1 significant figure)

2) 9.5 × 0.032 × 5006 = 1521.824 → 1.5×10^3 (2 s.f.)

3) 80 ÷ 55.4 = 1.444... → 1 (1 s.f.)

4) 13 × 24 = 312 → 3.1×10^2 (2 s.f.)

5) 6009 ÷ 22.10 = 271.900... → 271.9 (4 s.f.)

6) 5.258 × 14 × 5000 = 368060 → 4×10^5 (1 s.f.)

7) 0.002 × 0.093 = 0.000186 → 2.0×10^-4 (0.0002) (1 s.f.)

8) 4.7 × 37.251 = 175.0797 → 1.8×10^2 (180) (2 s.f.)

9) 603 ÷ 18.70 = 32.246... → 32.2 (3 s.f.)

10) 0.094 × 1.93 × 750 = 136.065 → 1.4×10^2 (140) (2 s.f.)

11) 2005 ÷ 87.66 = 22.8725... → 22.87 (4 s.f.)

12) 700 ÷ 15.1 = 46.3576... → 5.0×10^1 (50) (1 s.f.)

If you prefer a different convention for how many significant figures trailing zeros without a decimal indicate, tell me and I will re-round accordingly.
