$$\frac { x ^ { 2 } } { 9 } - \frac { y } { 25 }$$
Evaluate
$\frac{x^{2}}{9}-\frac{y}{25}$
Short Solution Steps
To add or subtract expressions, expand them to make their denominators the same. Least common multiple of $9$ and $25$ is $225$. Multiply $\frac{x^{2}}{9}$ times $\frac{25}{25}$. Multiply $\frac{y}{25}$ times $\frac{9}{9}$.
$$\frac{25x^{2}}{225}-\frac{9y}{225}$$
Since $\frac{25x^{2}}{225}$ and $\frac{9y}{225}$ have the same denominator, subtract them by subtracting their numerators.
