Let's solve each of these fraction division problems step by step. The general rule for dividing a fraction by a whole number is:
>
To divide a fraction by a whole number, multiply the fraction by the reciprocal of the whole number.
That is:
$$
\frac{a}{b} \div c = \frac{a}{b} \times \frac{1}{c}
$$
We'll apply this rule to each problem.

= \frac{5}{6} \div 2 = \frac{5}{6} \times \frac{1}{2} = \frac{5}{12}
$$
---
14. $ \frac{2}{6} \div 6 $
Simplify $ \frac{2}{6} = \frac{1}{3} $
$$
= \frac{1}{3} \div 6 = \frac{1}{3} \times \frac{1}{6} = \frac{1}{18}
$$
---
15. $ \frac{5}{8} \div 5 $
$$
= \frac{5}{8} \times \frac{1}{5} = \frac{5}{40} = \frac{1}{8}
$$
