Answer 5

sorry all i am trying to is figure out how to brake this down to the lowest terms

Answer 6

Is it (81/4 + 121/2) all divided by 3?

Answer 7

Your thought process should be this:
How can I change these fractions so I can just add them together?
The answer is this:
The lowest common integer that binds 4 3 and 2.
4*3=12
3*4=12
2*6=12
So to keep the same value on these integers you must keep the ratio. Thereby you multiply the numbers like this:
(81/4)*(3/3)
(121/2)*(6/6)
(91/3)*(4/4)
See what I did?
