Put Decimals In Order Of Size

Warm Up

Which is greater 0.9 or 0.12 ?

It is easier to see which is greater if we have the same number of decimal places in each number.

The most decimal places that we have in a number here is 2.
So, write each number with two decimal places using 0's where necessary.

0.90      0.12

Just as 90 is greater than 12
then 0.90 is greater than 0.12
so 0.9 is greater than 0.12

Example of an exam type question
Place these decimals in ascending order of size. 0.12 0.6 0.312 0.181
The most decimal places in any number is 3
so write all of the numbers with 3 decimal places.
0.120 0.600 0.312 0.181
We need the numbers in ascending order of size
so write (1) under the smallest then (2) under the next
and so on.
(1) (4) (3) (2)
Now write the original numbers
in the order given by (1), (2), (3) and (4)
0.12 0.181 0.312 0.6
