Best ResponseYou've already chosen the best response.0No, when you divide two fractions like\[\frac{(\frac{a}{b})}{(\frac{c}{d})}\]the algebra leads you to making this calculation:\[\frac{(\frac{a}{b})}{(\frac{c}{d})}=\frac{a}{b}\times \frac{d}{c}=\frac{ad}{bc}\]Notice the fraction on the bottom (denominator) has flipped before you multiply.

Best ResponseYou've already chosen the best response.0\[\frac{35}{17}=\frac{49}{16n}\]Multiply both sides by 16n to get\[\frac{35 \times 16n}{17}=49 \rightarrow \frac{560n}{17}=49\]Multiply both sides by 17 to then get,\[560n=49 \times 17 \rightarrow 560n=833\]and finally divide by 560 to isolate n\[n=\frac{833}{560}=\frac{119}{80}\]after simplifying.

Best ResponseYou've already chosen the best response.0^ 7 is a common factor of 833 and 560, so 833 = 7 x 119 560 = 7 x 80 The 7s cancel.
