We need to find the Lowest Common Denominator = LCD lowest is 100 10 x 10, 20, 30, 40, 50, 60, 70, 80, 90, 100 100 x 100, 200, 300, 400, 500, 600, 700, 800, 900, 1000. which is the lowest and common? 100 7/10 /100 how many times can 10 go into 100? 10 times. so we will multiply 10 time the numerator which is 7, and now will be 70/100 6/100 /100 how many times can 100 go into 100? 1 time. so we will multiply 1 time the numerator 6 which equals 6. 6/100 now add the new fractions. 70/100 + 6/100 = 76/100
