it is good to remember that when you multiply $9 \times \frac{8}{9}$ you can write it like this $\frac{9}{1} \times \frac{8}{9}$ you multiply top times top and bottom times bottom $\frac{9\times 8}{1\times 9}$ when you multiply you can change the order: $\frac{9\times 8}{9\times 1}$ that is the same as $\frac{9}{9} \times\frac{8}{1}$

everybody knows that a number divided by itself is 1 so $\frac{9}{9} = 1$ and you have $1 \times \frac{8}{1}$
