### What's Wrong? Q8(a) v1

1. 4m - n / m + n does not equal to 4m/m+2n

Owen here.

2. The algebra in the fractions can not be moved around . And 4m - n / m + n ≠ 4m/m+2n . 4m/m+2n ≠ 4m+2n/m

3. When pulled up, it should change its expression, for example, if it is /+2, when pulled up it should be -2

4. You can't just move ur expressions like that whenever you want...Test out the sums with ur calculator it doesn't make sense...That's what I did for this question also

5. n became 2n without any multiplication or division and 2n was initially in the denominator but was moved to the numerator.

6. suppose to be n become 2n, then u never drag down the n to the next equation.

7. 4m/m+2n is not equal to 4m+2n/m

8. we cannot move the expressions like this. This person can go check back and will find the results are diff.

9. 4m-n / m+n is not the same as 4m/m+2n and the person also left out the '2n' in the next step.

10. Numerators and denominators are different.Therefore, you cannot move the expressions anywhere that you want them to be.

11. (4m-n)/(m+n) does not equal to 4m/(m+2n). We cannot do cancellation unless we found out the sums already or there are things to cancel for both.

12. 4m-n cannot be moved or changed

13. You cannot shift the n to the denominator.

14. You cannot just move the algebraic expressions up and down, you can only do cancellation.

15. He cannot move 2n over the / sign

16. Transfer error.
5/1-(4m-5/m-n)
become 5/1-(4m/5m+2n)

17. 4m-n/m+n IS NOT equal to 4m/m+2n

18. One cannot swap the denominator to the numerator.

19. In the second step, the person changed the denominator of the fraction to m+2n.After that ,he moved the 2n from the denominator to the numerator.
