Fractions: Adding and Subtracting Like Denominators
2
3 4 Parts of a Fraction = the number of parts
= the total number of parts that equal a whole
3
Parts of a Fraction 3 = numerator 4 = denominator
4
Adding Like Denominators
Only add the numerators 1/4 1/4 3 1 4 + = 4 4 4 1/4 1/4
5
Add these fractions 1/5 1/5 3 1 4 + = 1/5 5 5 5 1/5
6
Add these fractions 1/4 1/4 2 1 3 + = 4 4 4 1/4
