Answer

True

Work Step by Step

We use the rule $\frac{a^{m}}{a^{n}}=a^{m-n}$ to help us cancel out the common factors of $x$ in the numerator and the denominator: $\frac{-5x^{2}y}{10x}$ =$\frac{-5}{10}\times \frac{x^{2}}{x}\times y$ =$\frac{-1}{2}\times x^{2-1}\times y$ =$-\frac{1}{2}\times x\times y$ =$-\frac{xy}{2}$ Since this answer matches the one in the statement, the statement is true.
