Best ResponseYou've already chosen the best response.1\[\frac{a}{b} \frac{\text{ rev }}{\text{ min }} \\ \text{ I like to think this means } a \text{ rev } \text{ R }b \text{ min } \\ \text{ treating } R \text{ like a equal sign }\] now we want to know x such that we have 517 rev that we want to find x in 517 rev R x min ... \[a \text{ rev } \text{ R } b \text{ min} \\ \text{ divide both sides by } a \\ 1 rev R \frac{b}{a} \text{ min} \\ \text{ multiply both sides by } 517 \\ 517 \text{ rev }R \frac{517 \cdot b}{a} \text{ min }\] however this is the way I used to solve it you can also setup equivalent ratios and solve that way \[\frac{a}{b} =\frac{517}{x}\] and solve for x

Best ResponseYou've already chosen the best response.1I just used a/b for your 34 4/9 mixed fraction thing you may want to convert that to improper fraction

Best ResponseYou've already chosen the best response.0\[\frac {rev} {time} = 34 + \frac {4}{9 } \] \[\frac {517} {time} = 34 + \frac {4}{9 } \]

Best ResponseYou've already chosen the best response.1\[34 \frac{4}{9} =\frac{34(9)+4}{9} =\frac{310}{9} \\ \text{ so you have } \\ \frac{310}{9}=\frac{517}{x}\]

Best ResponseYou've already chosen the best response.1can you solve that for x?

Best ResponseYou've already chosen the best response.1that says 310 rev per 9 min is equal to 517 rev per x min where we found x to be 4653/310 which is approximately 15 min

Best ResponseYou've already chosen the best response.0I had that number! And when i tried to convert it to a mixed fraction it all got messed up! lol thank you so much! I'm currently 8 months pregnant and my child is eating up my brains. ):
