Dividing decimals, step by step
Dividing a decimal by a whole number keeps the point exactly where it is.
The question
19.24 ÷ 2
19.24÷2
19.24÷2=9.62
9.62×2=19.24
- The number you are dividing by is already whole, so there is nothing to move: divide as usual and the point in the answer comes straight down.
- Now divide: 19.24 ÷ 2 = 9.62.
- Check it the other way round: 9.62 × 2 should give 19.24 back. A point in the wrong place fails this instantly — 19.24 and a tenth of it are not close.
