Simplify $\frac{2}{3}+\frac{1}{4}+\frac{5}{6}$

$1\frac{3}{4}$

CORRECT

$\frac{8}{13}$

$\frac{11}{12}$

$1\frac{1}{6}$

$1\frac{1}{3}$

Find the least common denominator (LCD) and convert each fraction to the LCD and then add. Simplify as necessary.

$\frac{2}{3}+\frac{1}{4}+\frac{5}{6}=\frac{8}{12}+\frac{3}{12}+\frac{10}{12}=\frac{21}{12}$

The result is an improper fraction because the numerator is larger than the denominator and can be simplified and converted to a mix numeral.

$\frac{21}{12}=\frac{7}{4}=1\frac{3}{4}$
