Answer
$-3xy/5$
Work Step by Step
In order to simplify fractions, we want to cancel out anything that is in both the numerator and the denominator of the fraction. In order to do this, we look for common factors for the values in the numerator and the denominator of the fraction. $-15x^{2}y$ and 25x have a common factor of 5x, so we simplify:
$5x(-3xy)/5x(5)=-3xy/5$
