Hayley baked a cheesecake. She used 5/8 pound sugar, and 6/8 pound peaches. How much did the ingredients weigh altogether?

Well, what you would need to do first is add the numerators and keep the denominators, so:

5/8 + 6/8 = 11/8

Now 8 goes into 11 once, so:

11-8=3

So you have 1 and you put the 3 over the 8, so your answer is 1 and 3/8

1 and 3/8 pound is my guess
