Example 4: Arrange the fractions , , ,, in descending order.
6 10 8 7 9
Solution: Since, the numerators of the given fractions are same, so, the fraction
with greater denominator will be the smaller fraction.
Comparing denominators of the given fractions, 10 > 9 > 8 > 7 > 6.
5 5 5 5 5
Thus, the fractions in descending order are: > > > > .

AddiTion And SubTrAcTion of Like frAcTionS
Addition of Like fractions
Look at the given diagram.
+
2 1 21 3 + =
So, + = = 2 1 3
5 5 5 5 5 5 5
We observe that the resultant fraction has the sum of numerators of two given
fractions and the same denominator.
Thus, to add like fractions, we follow these steps.
Step 1: Add the numerators.
Step 2: Keep the common denominator same.
Step 3: Reduce the fraction to its simplest form or convert it into mixed fraction,
if required.
