Answer
False; $\frac{1}{3}$
Work Step by Step
This is false because you cannot reduce a fraction unless it is a single term in the numerator or if you factor something from the entire numerator. Instead you should find the sum in the numerator first and then reduce the fraction.
$\frac{3+7}{30}$=$\frac{10}{30}$=$\frac{1}{3}$
