Explicație pas cu pas:

Salutare!

$\large \bf \dfrac{6}{15}: \dfrac{21}{25}:\dfrac{62}{9}=$

$\large \bf \dfrac{6}{15}\cdot \dfrac{25}{21}\cdot\dfrac{9}{62}=\dfrac{\not6}{\not15}\cdot \dfrac{\not25}{\not21}\cdot\dfrac{\not9}{62}=$  

$\large \bf \dfrac{2}{1}\cdot \dfrac{5}{7}\cdot\dfrac{3}{62}=\dfrac{2\cdot 5\cdot 3}{7\cdot 62}=$

$\large \bf \dfrac{\not2\cdot 5\cdot 3}{7\cdot\not 62}= \dfrac{5\cdot 3}{7\cdot 31}=$

$\color{Purple}\large \boxed{\bf \dfrac{15}{217}}$
