Question

Put the phone numbers in order from least to greatest.
1.26, 1.3, 1.2

Answer 1

least 1.2, 1.26, 1.3 greatest

Answer 2

1.2;1.26;1.3
You can add a zero to the end of each decimal, so it can change to make it easier.
1.26 doesn't change, 1.3 can be 1.30, and 1.2 can be 1.20.

So you can compare them like this
1.26
1.30
1.20
Just line them up and make sure they are all the same length, you can only do this to a decimal.
