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

Question 150145: Question:
find an expression equivalent to the one below
(0.3667)(0.8333)(0.3333)/(0.4444)(0.6667)(0.125)
the correct answer is:
[(11/30)(5/6)(1/3)/(4/9)(2/3)(1/8)]
= 11/4
= 2.75
I understand how to turn everything into fractions but the explanation in the answer states "Simplify the fraction in the beginning of the solution...". How do you go about simplifying [(11/30)(5/6)(1/3)/(4/9)(2/3)(1/8)] to get to the next step 11/4?
regards,
Tres.
