Question

which expression uses a common denominator to rewrite \\(\frac{1}{12} + \frac{1}{4}\\)? \\(\frac{1}{12} + \frac{3}{12}\\) \\(\frac{12}{12} + \frac{4}{4}\\) \\(\frac{12}{4} + \frac{12}{3}\\) \\(\frac{1}{12} + \frac{1}{12}\\)

Explanation:

Step1: Find common denominator

The denominators are 12 and 4. The least common denominator is 12.

Step2: Rewrite fractions

$\frac{1}{4} = \frac{1×3}{4×3} = \frac{3}{12}$

Step3: Combine rewritten fractions

$\frac{1}{12} + \frac{3}{12}$ is the correct expression.

Answer:

$\frac{1}{12} + \frac{3}{12}$
