Step 1 of 4
- One whole, cut into ten tenths.
- Look closely at one tenth.
- That tenth cut into ten hundredths.
- Ten tenths fill one whole.
The rule
Cut a tenth into ten parts. Each part is a hundredth. Ten hundredths make one tenth.
A little more than 3.4 can mean 3.4 plus a few hundredths. For example, 3.4 and 6 hundredths is 3.46.
Cut a hundredth into ten parts. Each part is a thousandth.
| Column | Written | How many make one whole |
|---|---|---|
| Tenths | 0.1 | 10 |
| Hundredths | 0.01 | 100 |
| Thousandths | 0.001 | 1000 |
0.25 is 2 tenths and 5 hundredths. It is also 25 hundredths. 2 tenths are 20 hundredths, and 20 + 5 = 25.
One kilogram is 1000 grams, or 1000 g. So one gram is a thousandth of a kilogram.
