Question 152013: I need help with these two problem please.

7 3/4 - 3 1/3 (7 and 3 over 4 (-minus) 3 and 1 over 2)

Hi Stanbon, thank you very much for your help. One thing, I don't understand the 7 and 3 over 4 -3 and 1 over 2 problem. I don't understand how you got the 14 over 2 at the end.

Rewrite the division problem before solving 1/4 divided 1/2
I need to know which one is correct:
1. 4/1 x 1/2

2. 4/1 x 2/1

3. 1/4 x 2/1

4. 1/4 x 1/2
