In this section we will look at the place values to the right of the decimal point.
In the example questions, work out the answer then click
to see whether you are correct.
Example
What is the value of the '6' in the number 2.164?
Comparing these numbers is easier if we write all the numbers with the same number of decimal places.
Now we have: 0.500, 0.950, 0.905, 0.590, 0.600, 0.900
The extra "0"s on the end make no difference to the value of the number, but they are easier to compare.
We can now see that sorting these numbers gives:
0.500, 0.590, 0.600, 0.900, 0.905, 0.950
After removing the extra "0"s, the final answer is: 0.5, 0.59, 0.6, 0.9, 0.905, 0.95
Example
Sort these numbers into order:
0.7, 0.27, 0.72, 0.702, 0.207, 0.2
