1) Cancel out the common factor which in this case is 8 $\frac{16m^2}{24m^7} = \frac{2m^2}{3m^7}$

2)First apply exponent rule $\frac{n(n+7)}{4n(n+7)}\\$ now cancel out the common factors which are n and n+7 leaving you with $\frac{1}{4}=0.25$

3)Factorize $\frac{(x+2)(x-12)}{x+2}$ cancel out the common factor in this case x+2 leaving you with $x-12$

4) Factorize $\frac{(-3w+1)(3w-1)}{4(3w-1)}$ cancel out the common factor in this case 3w-1 leaving you with $\frac{-3w+1}{4}$

5) In the picture
