What is the sum of 1/12, 1/9, and 1/4?

What is the sum of 1/12, 1/9, and 1/4?

• A. 2/3
• B. 3/4
• C. 4/9
• D. 1/2

Answer: (C)

To find the sum of the fractions \( \frac{1}{12} \), \( \frac{1}{9} \), and \( \frac{1}{4} \), you first need to find a common denominator. The least common multiple (LCM) of the denominators 12, 9, and 4 is 36. Now, convert each fraction to have this common denominator: 1. Convert \( \frac{1}{12} \) to have a denominator of 36: \[ \frac{1}{12} = \frac{1 \times 3}{12 \times 3} = \frac{3}{36} \] 2. Convert \( \frac{1}{9} \) to have a denominator of 36: \[ \frac{1}{9} = \frac{1 \times 4}{9 \times 4} = \frac{4}{36} \] 3. Convert \( \frac{1}{4} \) to have a denominator of 36: \[ \frac{1}{4} = \frac{1 \times 9}{4 \times 9} =

To find the sum of the fractions ( \frac{1}{12} ), ( \frac{1}{9} ), and ( \frac{1}{4} ), you first need to find a common denominator. The least common multiple (LCM) of the denominators 12, 9, and 4 is 36.

Now, convert each fraction to have this common denominator:

1. Convert ( \frac{1}{12} ) to have a denominator of 36:

[

\frac{1}{12} = \frac{1 \times 3}{12 \times 3} = \frac{3}{36}

]

2. Convert ( \frac{1}{9} ) to have a denominator of 36:

[

\frac{1}{9} = \frac{1 \times 4}{9 \times 4} = \frac{4}{36}

]

3. Convert ( \frac{1}{4} ) to have a denominator of 36:

[

\frac{1}{4} = \frac{1 \times 9}{4 \times 9} =
