3.2 Comparing and Ordering Fractions and Decimals

Focus - Use Benchmarks, place value and equivalent fractions to compare and order fractions and decimals.

To order Fractions and decimals use 1 of the following 3 methods:


Method #1 - Construct a number line complete with Benchmarks. Estimate the position of each number.

Eg. 0.25, 3/8, 2/3, 3/4

._________________.________________.

Put these numbers in order from least to greatest:

Method #2 - Change all numbers to decimals and then compare their place value.

Eg. 3 1/8 =

11/3 =

3.25 =


Eg. 2.33 =

2 4/10 =

7/2 =



Method #3 - Change all numbers to equivalent fractions that have the same denominator.

Eg.
4.3 =

4 1/5 =

4 ½ =


Any fraction greater than 1 can be written as a mixed number - a number that contains a whole number and a fraction.
