Question

James bought 2/3 pound of red apples, 3/4 pound of green apples, and 5/6 pound of yellow apples. How many pounds of apples did James buy altogether

Answer 1

Ok, so we can't solve that because all of the fraction's denominators are different, so we need to find a common denominator for all of the fractions. The lowest common denominator is 12. So to get twelve we multiply the denominator and numerator to get the denominator. So in 3/4 we multiply the 4 by 3 and the 3, so we get 9/12. In 2/3 we multiply the 3 by 4 and the 2 by 4 and we get 8/12. Finally, in 5/6 you multiply the 6 by 2 to get 12, and the 5 by 2, and you get 10/12. So 10/12 + 8/12 + 9/12 = 27/12 = 2 3/12, or 2 1/4.
