Ensure that the denominators are the same when adding or subtracting fractions.
adding fractions is like adding a WHOLE lot of parts of numbers
When adding or subtracting fractions their denominators must be the same
Used for adding dissimilar fractions
What is the definition of Adding and Subtracting Like Fractions
Mixed numbers can be converted to improper fractions. Then, it is exactly the same as adding proper ones.
For adding or substracting fractions first of all we should calculate the LCM( Lowest Common Multiplier) of the denominators in both of the fractions.
Yes, you must.
Before adding or subtracting two fractions they are converted into like fractions. Explain with examples why this is necessary.
If their denominators are different then find their lowest common denominator by means of their lowest common multiple remembering to adjust their numerators accordingly before adding or subtracting.
