Unformatted text preview: o Change the numerators of each fraction o Add or subtract the numerators (keep denominator unchanged) o Reduce Examples: 1. = + 5 1 4 1 2. = + 8 3 6 5 3. = + + 10 3 6 1 5 2 5 4. =6 1 5 2 5. =4 1 2 5 1 3 6. =+ 10 3 5 4 2 1 6 7. =+ 10 3 5 1 3 4 1 2 8. = + 4 5 4 Multiplying and Dividing Fractions: o Simplify the fractions if not in lowest terms. o Multiply the numerators of the fractions to get the new numerator. o Multiply the denominators of the fractions to get the new denominator. Examples: 1. 3 2 5 1 × 7 2. = × 3 2 8 5 3. = × 6 5 4 Dividing Fractions: o Multiply the first fraction by the reciprocal of the second Examples: 1. = ÷ 7 6 2 3 2. = ÷ 11 8 5 4 8 3. = ÷ 8 9 4 4. = 7 2 5 4 5. =  9 2 10 7...
