Question

4m-4n divided by 4m+4n

Answer 1

`(4m-4n)/(4m+4n)`

Take out 4 as a common factor for both the numerator and the denominator:


`= (4(m-n))/(4(m+n))`


`= (m-n)/(m+n)`

------------------------------------------

`\bf \text { Answer = } (m-n)/(m+n)`
------------------------------------------

Answer 2

`(4m-4n)/(4m + 4n) = 0`

Eventually 4m and 4n will cancel out because the above portion is a negative and the below is a positive.
