Answer:
2 1/2 rolls of ham
Explanation:
Break down the question. 1/4 is for 1 slice of cheese. So if she is going to use 1 1/4 now. That means that would be equal to 5 slices of cheese. Now look at the ham. It allows you to start with 1/2 rolls of ham. To make it equal to the 5 slices of cheese. You will do add 1/2 together 5 times. Adding 1/2 and 1/2 is 1. So if you do that another two times. Its now 2. Add one more 1/2 now you have 2 1/2.
