Question

determimati o fractie care inmultita cu 4/9 da produsul 32/81​

Answer 1

$\frac{x}{y} \times \frac{4}{9} = \frac{32}{81}$

rezulta

$\frac{x}{y} = \frac{ \frac{32}{81} }{ \frac{4}{9} }$

rezulta

$\frac{x}{y} = \frac{32 \times 9}{81 \times 4}$

se simplifica cu 9

$\frac{x}{y} = \frac{32}{36} = \frac{16}{18} = \frac{8}{9}$
