2/3 + 2/4 Find a common denominator whatever you do to the denominator you do to the numerator. 2 x 4 and 3 x 4 = 8/12 2 x 3 and 4 x 3 = 6/12 Add 8 and 6 8+6=14 14/12 Now because it is an improper fraction ask how many times 12 goes into 14. 1 Then the remainder is your numerator and the denominator stays the same. 1 2/12 Now we need to find the lowest common multiple. They can both be divided by 2. 2÷2=1 12÷2=6 They can't be divided anymore so the answer is: 1 1/6
