select one answer

a. \\\frac{9}{100}\\

b. \\\frac{9}{110}\\

c. \\\frac{27}{100}\\

d. \\\frac{14}{1000}\\

Explanation:

Find equivalent fraction with common denominator

$$ \frac{2}{10} = \frac{2 \times 10}{10 \times 10} = \frac{20}{100} $$

Add the numerators over the common denominator

$$ \frac{20}{100} + \frac{7}{100} = \frac{20 + 7}{100} = \frac{27}{100} $$

• (A) \(\frac{9}{100}\)
• (B) \(\frac{9}{110}\)
• (C) \(\frac{27}{100}\) (Correct answer)
