    a) 4$\dfrac{5}{7}$ : 1$\dfrac{5}{6}$ + 2$\dfrac{7}{15}$ x $\dfrac{21}{74}$
    ⇔ $\dfrac{33}{7}$ : $\dfrac{11}{6}$ + $\dfrac{37}{15}$ x $\dfrac{21}{74}$
    ⇔ $\dfrac{33}{7}$ x $\dfrac{6}{11}$ + $\dfrac{7}{10}$
    ⇔ $\dfrac{18}{7}$ + $\dfrac{7}{10}$
    ⇔ $\dfrac{229}{70}$

    b ) 3 $\dfrac{5}{7}$ – 2$\dfrac{5}{7}$ + 6$\dfrac{3}{8}$
    = $\dfrac{26}{7}$ – $\dfrac{19}{7}$ + $\dfrac{51}{8}$
    = $\dfrac{717}{56}$
    c ) 4 $\dfrac{1}{2}$+ $\dfrac{1}{2}$ : 5$\dfrac{1}{2}$
    = $\dfrac{9}{2}$ + $\dfrac{1}{2}$ x $\dfrac{2}{11}$
    = $\dfrac{9}{2}$+ $\dfrac{1}{11}$
    = $\dfrac{101}{22}$
    d ) 3$\dfrac{1}{4}$ +  $\dfrac{2}{34}$ + $\dfrac{5}{7}$
    = $\dfrac{13}{4}$ + $\dfrac{92}{119}$
    = $\dfrac{1915}{476}$
