$$\frac{1}{4}$$ is greater than $$\frac{1}{8}$$
Explanation:
make denominator equal for $$\frac{1}{4}$$ and  $$\frac{1}{8}$$
$$\frac{1}{8}$$ = $$\frac{1}{8}$$
$$\frac{1}{4}$$ = $$\frac{1}{4}$$ X $$\frac{2}{2}$$ =  $$\frac{2}{8}$$
If the denominators are the same, then the fraction with the greater numerator is the greater fraction.
