Answer 1

The number of decimal places in a product equals the sum of the decimal places in the factors.

- 0.3 (1 dp) × 0.16 (2 dp) → 1 + 2 = 3 decimal places.
- 2.9 (1 dp) × 5.3 (1 dp) → 1 + 1 = 2 decimal places.
- 1.9 (1 dp) × 4.02 (2 dp) → 1 + 2 = 3 decimal places.
- 1.7 (1 dp) × 3.1204 (4 dp) → 1 + 4 = 5 decimal places.
- 9.07 (2 dp) × 4.03 (2 dp) → 2 + 2 = 4 decimal places.
