(-3/8) / (5/9)
when dividing fractions, you " flip " what you are dividing by, then multiply. Make sure you flip the right number.
(-3/8) * (9/5) --- see how I flipped what I was dividing by...now just multiply
-27/40
and thats it :)

Yep, just as I explained in your previous question.

$$\frac{\frac{a}{b}}{\frac{c}{d}} = \frac{a}{b}*\frac{d}{c} = \frac{a*d}{b*c}$$
