`5/11 : 5/6 + 7/55 =5/11 xx 6/5 + 7/55 =6/11 + 7/55= 30/55 + 7/55= 37/55`
\(\dfrac{5}{11}:\dfrac{5}{6}+\dfrac{7}{55}=\dfrac{5.6}{11.5}+\dfrac{7}{55}=\dfrac{6}{11}+\dfrac{7}{55}=\dfrac{30}{55}+\dfrac{7}{55}=\dfrac{37}{55}\)
\(\dfrac{5}{11}:\dfrac{5}{6}+\dfrac{7}{55}=\dfrac{5\times6}{11\times5}+\dfrac{7}{55}=\dfrac{6}{11}+\dfrac{7}{55}+\dfrac{30}{55}+\dfrac{7}{55}=\dfrac{30+7}{35}=\dfrac{37}{55}\)
