Answer
$\frac{8}{11}$
Work Step by Step
$\frac{7}{22}+\frac{3}{22}+\frac{3}{11}$
now the least common multiple of 22 & 11 is 22. so multiply the nominator and denominator of third fraction with 2.
$\frac{7}{22}+\frac{3}{22}+\frac{3\times2}{11\times2}$
=$\frac{7}{22}+\frac{3}{22}+\frac{6}{22}$
Add numerators, as all fractions have same denominator
= $\frac{7+3+6}{22}$
= $\frac{16}{22}$
= $\frac{16\div2}{22\div2}$ (divide by common factor 2)
= $\frac{8}{11}$
