What is the definition of Adding and Subtracting Like Fractions
The Lowest Common Denominator is needed when adding or subtracting fractions.
Because to add or subtract two fractions you first have to find equivalent fractions for both which have the same denominator.
you must make the fractions equivalent and with the same denomenator
When adding or subtracting fractions their denominators must be the same
Ensure that the denominators are the same when adding or subtracting fractions.
Pulled and mulled
Before adding or subtracting two fractions they are converted into like fractions. Explain with examples why this is necessary.
