ADDITION AND SUBTRACTION OF FRACTIONS
4 + 2 = 6 8 – 1 = 75 5 5 6 6 6
When adding fractions with the same denominators, numerators are added together and the denominators remain unchanged.
When subtracting fractions with the same denominator from the numerator of the first fraction to subtract the numerator of the second fraction, the denominator remains unchanged
ADD AND SUBTRACT
1 + 2 = 4 – 1 =
5 5 6 6
4 + 1 = 7 – 3 =
6 6 3 3
3 + 5 = 9 – 2 =
