Answer 1

Răspuns:  $\bf \dfrac{268}{187}$

Explicație pas cu pas:

Salutare!

$\bf \dfrac{100\dfrac{1}{2} }{70\dfrac{1}{8}} = \dfrac{\dfrac{2\cdot 100+1}{2} }{\dfrac{8\cdot 70 +1}{8}} = \dfrac{\dfrac{201}{2} }{\dfrac{561}{8}} =\dfrac{201}{2} : \dfrac{561}{8}=\dfrac{201}{2}\cdot \dfrac{8}{561}=\dfrac{201}{\not2}\cdot \dfrac{\not8}{561}=$

$\bf \dfrac{\not201}{1}\cdot \dfrac{4}{\not561}=\dfrac{67\cdot4}{1 \cdot 187}=\boxed{\bf \dfrac{268}{187}}$
