Mathematics - Fractions - Adding and subtracting fractions with like denominators - Add and Subtract Same Denominators
5 steps: (1) 2/7 + 3/7 = ? Think: 2 sevenths + 3 sevenths = 5 sevenths = 5/7. (2) Rule: Add the NUMERATORS, keep the DENOMINATOR. (3) Subtraction works the same: 5/8 - 2/8 = 3/8. (4) If the result can be simplified, do it: 4/6 + 2/6 = 6/6 = 1 whole! (5) What if sum > denominator? 4/5 + 3/5 = 7/5 = 1
