A fraction represents a part of a whole and is written as $$\frac{a}{b}$$ , where 'a' is the numerator and 'b' is the denominator.

How do you find a common denominator for $$\frac{3}{5}$$ and $$\frac{3}{10}$$ ?

The least common denominator (LCD) of $$5$$ and $$10$$ is $$10$$ .

Add $$\frac{3}{5} + \frac{3}{10}$$ .

$$\frac{3}{5} + \frac{3}{10} = \frac{6}{10} + \frac{3}{10} = \frac{9}{10}$$ .

What is the sum of $$\frac{5}{6} + \frac{1}{12}$$ ?

$$\frac{5}{6} + \frac{1}{12} = \frac{10}{12} + \frac{1}{12} = \frac{11}{12}$$ .

If a construction company hauls away $$\frac{1}{6}$$ and $$\frac{2}{6}$$ of a truckload, what is the total?

$$\frac{1}{6} + \frac{2}{6} = \frac{3}{6} = \frac{1}{2}$$ truckload.

What is the result of adding $$\frac{2}{4} + \frac{2}{4}$$ ?

$$\frac{2}{4} + \frac{2}{4} = \frac{4}{4} = 1$$ .
