Decimals in order
You learn to put decimals in order from smallest to largest.
How to work it out
- First compare the whole numbers before the decimal point.
- Then add zeros so they all have the same number of decimal places.
- Now you can compare them like whole numbers.
Put in order from smallest to largest: 0.5, 0.45, 0.405.
- Before the decimal point there is a 0 every time.
- Make them the same length: 0.500, 0.450 and 0.405.
- Now you compare 500, 450 and 405.
- So 0.405, 0.45, 0.5.
More examples
Put in order: 2.3 and 2.03.
2.30 and 2.03: so 2.03, then 2.3.
Put in order: 1.09 and 1.9.
1.09 and 1.90: so 1.09, then 1.9.
