Addition and subtraction of unlike fractions
When adding or subtracting unlike fractions we take the LCM of the denominators and convert the fractions into like fractions, then simplify.
For example, the denominators of the fractions given below are 4
and 3. The LCM of 4 and 3 is 12. Then the given fractions are converted into
like fractions and simplified as given below.
Simplification of Fractions
While simplifying fractions under the relation of basic operations ÷, ×,
+, - and with brackets, we need to follow the BODMAS rule.
