melanie has 4 2/3 pounds of chopped walnuts she uses 1 1/4 lb in the recipe how many pounds of chopped walnuts did she have left

To make the denominator the same on both sides you need to multiply 1/4 by three and make it 3/12 and multiply 2/3 by four to get 8/12 and then you just subtract to get 2 5/12
