Explanation:

Step1: Convert mixed - number to improper fraction

$1\frac{1}{2}=\frac{1\times2 + 1}{2}=\frac{3}{2}$

Step2: Find a common denominator

The common denominator of 2 and 7 is 14. $\frac{3}{2}=\frac{3\times7}{2\times7}=\frac{21}{14}$, $\frac{4}{7}=\frac{4\times2}{7\times2}=\frac{8}{14}$

Step3: Add the fractions

$\frac{21}{14}+\frac{8}{14}=\frac{21 + 8}{14}=\frac{29}{14}$

Step4: Convert improper fraction back to mixed - number

$\frac{29}{14}=2\frac{1}{14}$

Answer:

A. $2\frac{1}{14}$
