Question

REZOLVATI: 20 supra 35:(-4 supra 7) Repede!

Answer 1

$\frac{20}{35} : (\frac{-4}{7})$

$\frac{\frac{20}{35}}{\frac{-4}{7}}$

$=\frac{\frac{20}{35}}{-\frac{4}{7}}$

$=-\frac{\frac{20}{35}}{\frac{4}{7}}$

$=-\frac{20\cdot \:7}{35\cdot \:4}$

$=-\frac{20\cdot \:7}{140}$

$=-\frac{140}{140}$

$=-1$
