What is $\frac56$ of 30?
I want to find $\frac56$ of 30, which means I need to multiply $\frac56$ by 30. To do that, I can think of 30 as $\frac{30}{1}$, and then use the rule for multiplying fractions: multiply the numerators and the denominators. So I get $\frac56 \times \frac{30}{1} = \frac{5 \times 30}{6 \times 1} = \frac{150}{6}$. To simplify this fraction, I can divide both the numerator and the denominator by their greatest common factor, which is 6. So I get $\frac{150}{6} = \frac{150 \div 6}{6 \div 6} = \frac{25}{1}$. This is just 25, so the answer is 25.
