What is the sum of 1/2 + 1/3 + 1/9?

What is the sum of 1/2 + 1/3 + 1/9?

• A. 11/18
• B. 17/18
• C. 16/18
• D. 34/36

Answer: (B)

To find the sum of the fractions 1/2, 1/3, and 1/9, we first need to determine a common denominator for these fractions. The least common multiple of the denominators (2, 3, and 9) is 18. Next, we rewrite each fraction with this common denominator: - For 1/2: \[ \frac{1}{2} = \frac{1 \times 9}{2 \times 9} = \frac{9}{18} \] - For 1/3: \[ \frac{1}{3} = \frac{1 \times 6}{3 \times 6} = \frac{6}{18} \] - For 1/9: \[ \frac{1}{9} = \frac{1 \times 2}{9 \times 2} = \frac{2}{18} \] Now, we can add these fractions together: \[ \frac{9}{18} + \frac{6}{18} + \frac{2}{18} = \frac{9 + 6 +

To find the sum of the fractions 1/2, 1/3, and 1/9, we first need to determine a common denominator for these fractions. The least common multiple of the denominators (2, 3, and 9) is 18.

Next, we rewrite each fraction with this common denominator:

• For 1/2:

[

\frac{1}{2} = \frac{1 \times 9}{2 \times 9} = \frac{9}{18}

]

• For 1/3:

[

\frac{1}{3} = \frac{1 \times 6}{3 \times 6} = \frac{6}{18}

]

• For 1/9:

[

\frac{1}{9} = \frac{1 \times 2}{9 \times 2} = \frac{2}{18}

]

Now, we can add these fractions together:

[

\frac{9}{18} + \frac{6}{18} + \frac{2}{18} = \frac{9 + 6 +
