\frac{\left(5+3d\right)\left(-2\right)}{dt\left(15+9d\right)}
Divide \frac{5+3d}{dt} by \frac{15+9d}{-2} by multiplying \frac{5+3d}{dt} by the reciprocal of \frac{15+9d}{-2}.
\frac{-2\left(3d+5\right)}{3dt\left(3d+5\right)}
Factor the expressions that are not already factored.
\frac{-2}{3dt}
Cancel out 3d+5 in both numerator and denominator.
