------- = ??
5

Answer 8

Young math wiz gets the medal 4 answering first.

Answer 9

example:

2/5 - 4/7

first find the smallest number that both denominators (5 and 7) can go into. in this case it is 35.
so then you need to multiply the top and the bottom(numerator and denominator) of 2/5 by 7. and you need to multiply the Numerator and denominator of 4/7 by 5.

you will end up with

14/35 - 20/35

so now just subtract…
14-20= -6

your answer is -6/35

Answer 10

Nono only whole # minus fraction....

Answer 11

ok whats the problem

Answer 12

2 - 4/5

Answer 13

Ambiguity!

2 - 4/5, 3-2/7, etc..., are examples of combining integers with fractions.

I don't believe Brolex meant that he has to combine 2 - 4/5 with 3-2/7

Brolex: Please clarify what it is that you want to learn.

Answer 14

ok so 2 is the same as 2/1.
so then it is
2/1 - 4/5

since 1 can go into 5, just multiply the numerator and denominator of 2/1 by 5.

you will have 10/5 -4/5

10-4=6

answer: 6/5

Answer 15

But was that called for in the original problem?

Answer 16

What about 2 - 3/5

Answer 17

Yes it was

Answer 18

try what i showed you

2= 2/1

2/1 - 3/5

same steps as above

Answer 19

Answer 28

Still seeing ambiguity!

2 - 4/5, 3-2/7, etc...

Did you mean Fraction #2 is 4/5, and Fraction #3 is 2/7?

Brolex, would you mind stating your homework problem over again? We several people have invested a lot of time here and we're still unsure of what you're trying to do.

Brolex, you may not want my opinion any longer, but I think you and your helper would save a great deal of time and effort if you would PLEASE repeat every detail of the exact math problem that you want to solve. You and YoungMathWiz are losing a lot of valuable time, the way things are going.
