Full solution

Q. Add.

\newline

\frac{1}{4} + \frac{2}{12} =

____

\newline

Use the model to help you.

Find Common Denominator: Find a common denominator for the fractions $\frac{1}{4}$ and $\frac{2}{12}$ . The least common multiple of $4$ and $12$ is $12$ . $\frac{1}{4} = \frac{3}{12}$ (since $1\times3 = 3$ and $4\times3 = 12$ ) $\frac{2}{12}$ remains the same.
Add Fractions: Add the fractions now that they have the same denominator. $\frac{3}{12} + \frac{2}{12} = \frac{5}{12}$
