## ShadowCain one year ago Martina walked 3/4 of a mile in 3/5 of an hour. At this rate, how far can Martina walk in one hour?

1. freckles

$\frac{\frac{3}{4} \text{ mile }}{\frac{3}{5} \text{ hour }} =\frac{ ? \text{ mile }}{1 \text{ hour }}$ find the ? mark

A. 1 2/3 miles B. 9/20 of a mile C. 4/5 of a mile D. 1 1/4 miles

let me know if you need anymore help

I keep coming up with 11/4, but that's not one of my options

did you try to solve the equation I gave you above?

$\frac{\frac{3}{4}}{\frac{3}{5}}=\frac{x}{1} \\ \text{ or } \frac{\frac{3}{4}}{\frac{3}{5}}=x$ you are just dividing 3/4 by 3/5

can you try finishing from here? $x=\frac{\frac{3}{4}}{\frac{3}{5}} \cdot \frac{\frac{5}{3}}{\frac{5}{3}}$ let me know what you get after trying to do this multiplication on top and bottom

I'm not sure how to do that

$x=\frac{\frac{3}{4} \cdot \frac{5}{3}}{\frac{3}{5} \cdot \frac{5}{3}} \\ x=\frac{\frac{3(5)}{4(3)}}{\frac{3(5)}{5(3)}}$

hint 15/15 is just one anything divided by 1 is that anything $x=\frac{3(5)}{4(3)}$

15/12 = 1 1/4 miles
