$$\frac{1}{4} + \frac{1}{4} + \frac{1}{4} + \frac{1}{4} = \frac{4}{4}$$ .

The sum is $$\frac{6}{6}$$ .

The denominator is the bottom number of a fraction that shows how many equal parts the whole is divided into.

The numerator is the top number of a fraction that shows how many parts are being considered.
