Kieth has 8 1/2 cups of flour. he uses 5 2/3 cups to make muffins. how many cups of flour does keith have left?

Hi there!

First, we need to make the denominators of the fractions the same. This can be done by multiplying 1/2 by 3/3 and 2/3 by 2/2. This gives us the fraction 3/6 and 4/6. We can subtract 4/6 from 3/6 to get -1/6, which will need to be taken out of the fraction later. Lastly, we will subtract 8-5 to get 3, of which we also need to subtract 1/6 from that. Therefore, Keith has 2 5/6 cups of flour left.

Hope this helps!! :)
