Best ResponseYou've already chosen the best response.0Replace the variable with the numbers they're equal to \[3\left( \frac{ 3 }{ 4 } \right)\left( \frac{ 5 }{ 9 } \right)\left( \frac{ 8 }{ 15 } \right)\] You can write 3 as 3/1 if it makes it easier \[\left( \frac{ 3 }{ 1 } \right)\left( \frac{ 3 }{ 4 } \right)\left( \frac{ 5 }{ 9 } \right)\left( \frac{ 8 }{ 15 } \right)\] From here, you can cancel common factors and then multiply. Or multiply and then reduce at the end

Best ResponseYou've already chosen the best response.0There are 3 negative signs, so the answer is negative. So you're left with 2/3

Best ResponseYou've already chosen the best response.0It's definitely better to cancel when you can because then you're not left with big numbers, and you might not even have to multiply anything. To show your work, maybe write the problem once, then write it again showing the canceling. Your teacher should understand that as written, it's pretty common
