Ordering Fractions and Converting between fractions and decimals

When ordering fractions there are two main ways to do this

1) Convert each fraction to a decimal and then order

                                        or
2) Write each fraction over a common denominator.

Example of method 2)


 




















If we are to use method one we need to know how to convert fractions to decimals.  Some are easy such as 1/2 = 0.5 and 1/4 = 0.25.

If we come across a fraction that we do not know as a decimal and we cannot compare it to percentages to help us we can use division to help us.
