Best ResponseYou've already chosen the best response.0Hint. Like terms cancel out. So it's just 1/45

Best ResponseYou've already chosen the best response.1\(\dfrac{9(8)}{9(4) \times 9(10)} =\) \(=\dfrac{72}{36 \times 90} \) \(=\dfrac{\cancel{72}~2}{\cancel{36}~1 \times 90} \) \(= \dfrac{2}{90} \) \(= \dfrac{1}{45} \)

Best ResponseYou've already chosen the best response.0@sh3lsh : is 9 times (4), not 8 so you can't : 9*2*4

Best ResponseYou've already chosen the best response.1@Leong @sh3lsh did it correctly. The 2 in 9 * 2 * 4 in the denominator comes from the 10 which is 2 * 5. This is how he did it: \(\dfrac{9(\color{red}{8})}{9(\color{blue}{4}) \times 9(\color{green}{10})} =\) \(=\dfrac{9 \times \color{red}{4 \times 2}}{9 \times \color{blue}{(1) \times 4} \times 9 \times \color{green}{2 \times 5}} \) \(=\dfrac{9 \times \color{red}{4 \times 2}}{9 \times \color{blue}{4} \times \color{green}{2 \times \color{blue}{(1) } \times 9 \times 5}} \) \(=\dfrac{\cancel 9 \times \cancel 4 \times \cancel 2 ~1}{\cancel 9 \times \cancel 4 \times \cancel 2 \times (1) \times 9 \times 5} \) \(= \dfrac{1}{45} \) \(=\dfrac{1}{45} \)
