Question

$( \frac{34}{12} ) \div ( \frac{42}{10} )$
como é que se e
resolve?​

Answer 1

Divisão de frações

$\boxed{\boxed{\mathsf{\dfrac{a}{b}\div\dfrac{c}{d}=\dfrac{a}{b}\times\dfrac{d}{c}}}}$

$\dfrac{34}{12}\div\dfrac{42}{10}=\dfrac{34}{12}\times\dfrac{10}{42}\\\dfrac{340\div4}{504\div4}=\dfrac{85}{126}$

Portanto

$\boxed{\boxed{\mathsf{\dfrac{34}{10}\div\dfrac{10}{42}=\dfrac{85}{126}}}}$
