Explicație:
[tex]\bf 1\dfrac{1}{7} \cdot 4\dfrac{2}{3} :\dfrac{2}{3} =[/tex]
[tex]\bf \dfrac{1\cdot 7 + 1}{7} \cdot \dfrac{4\cdot 3+2}{3} \cdot \dfrac{3}{2} =[/tex]
[tex]\bf \dfrac{\not8}{\not7} \cdot \dfrac{\not14}{\not3} \cdot \dfrac{\not3}{\not2} =[/tex]
[tex]\bf \dfrac{4}{1} \cdot \dfrac{2}{1} \cdot \dfrac {1}{1} =[/tex]
[tex]\bf 4 \cdot 2 =\red{\underline{~8~}}[/tex]
