How it works
Do the whole numbers first. Count the places. The point drops straight down.
0.6 × 2: 6 × 2 = 12, and one place after the point gives 1.2.
To divide, divide as if there were no point, then put the point straight above.
Worked examples
Times
- The answer digits are 12 for 0.6 × 2: where does the point go?
- Whole numbers: 6 × 2 = 12.
- 0.6 has one place, so 1.2.
- So the answer is 1.2.
Divide
- The answer digits are 27 for 1.35 ÷ 5: where does the point go?
- Whole numbers: 135 ÷ 5 = 27.
- 1.35 has two places, so 0.27.
- So the answer is 0.27.
Divide with a point
- 17.55 ÷ 9
- 17.55 ÷ 9: share each place.
- The point goes straight above in the answer.
- So the answer is 1.95.
