a\leq 10\left(-\frac{3}{2}\right)
Multiply both sides by -\frac{3}{2}, the reciprocal of -\frac{2}{3}. Since -\frac{2}{3} is negative, the inequality direction is changed.
a\leq \frac{10\left(-3\right)}{2}
Express 10\left(-\frac{3}{2}\right) as a single fraction.
a\leq \frac{-30}{2}
Multiply 10 and -3 to get -30.
a\leq -15
Divide -30 by 2 to get -15.
