How to Compare and Order Decimals
Decimals can be compared and ordered using number lines as visual aids. Let's delve into this concept:
Examples
Example: 1- On the number line below we can see that 2.3 (two and three tenths) is less than 2.8 (two and eight tenths).
- 2.8 is five tenths more than 2.3.
Example: 2
- Look at this next example.
- 6.82 (six and eighty-two hundredths) is less than 6.86 (six and eighty-six hundredths).
- 6.82 is more than 6.8 (six and eight tenths or six and eighty hundredths).
- 6.86 is less than 6.9 (six and nine tenths or six and ninety hundredths).
- If we order the four decimals from smallest to biggest we get: 6.8, 6.82, 6.86, 6.9.
Example: 3
- On this next number line we can see that 5.5 (five and five tenths) is less than 5.6 (five and six tenths), which is less than 5.9 (five and nine tenths).
- The difference between the biggest number and the smallest number is seven tenths.
- If we order the decimals from smallest to biggest we get: 5.2, 5.6, 5.9.
Example: 4
- In this next number line 4.23 (four and twenty-three hundredths) is less than 4.27 (four and twenty-seven hundredths).
- 4.27 is four hundredths more than 4.23.
