(3+7/11)*1/4-1/22 ----------------------- (5-3/11):13+1/2

$\frac{(3+\frac{7}{11})*\frac{1}{4}-\frac{1}{22}}{(5- \frac{3}{11}):13+\frac{1}{2}}$ =1
1) $3+\frac{7}{11}=3\frac{7}{11}=\frac{40}{11}$
2) $\frac{40}{11}*\frac{1}{4}=\frac{10}{11}$
3) $\frac{10}{11}-\frac{1}{22}=\frac{20}{22}-\frac{1}{22}=\frac{19}{22}$
4) $5-\frac{3}{11}=4\frac{11}{11}-\frac{3}{11}=4\frac{8}{11}=\frac{52}{11}$
5) $\frac{52}{11}:13=\frac{52}{11*13}=\frac{4}{11}$
6) $\frac{4}{11}+\frac{1}{2}=\frac{8}{22}+\frac{11}{22}=\frac{19}{22}$
7) $\frac{19}{22}:\frac{19}{22}=\frac{19*22}{22*19}=1$
