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

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.
