Answer 1

Answers (rounded to the correct number of significant figures — set by the factor with the fewest s.f.):

1) 2 × 56.250 × 8000
- Fewest s.f. = 1 (from 2 and 8000)
- Exact product = 900000 → rounded to 1 s.f. = 9 × 10^5

2) 6.45 × 0.4
- Fewest s.f. = 1 (from 0.4)
- Exact product = 2.58 → rounded to 1 s.f. = 3

3) 0.02 × 0.093
- Fewest s.f. = 1 (from 0.02)
- Exact product = 0.00186 → rounded to 1 s.f. = 0.002 (2 × 10^-3)

4) 9.6 × 0.004
- Fewest s.f. = 1 (from 0.004)
- Exact product = 0.0384 → rounded to 1 s.f. = 0.04 (4 × 10^-2)
