Question

cat este (5supra2 minus24supra25 ori(25supra16 minus 3supra8))impartit la 6supra5​

Answer 1

$( \frac{5}{2} - \frac{24}{25} ) \times ( \frac{25}{16} - \frac{3}{8} ) \div \frac{6}{5}$

Amplifici in cele 2 paranteze

$= ( \frac{125}{50} - \frac{48}{50} ) \times ( \frac{25}{16} - \frac{6}{16} ) \div \frac{6}{5}$

$= \frac{77}{50} \times \frac{19}{16} \div \frac{6}{5}$

Cand imparti la o fractie, inversezi numitorul cu numaratorul si faci in loc inmultire

Adica

$\div \frac{6}{5} \: \: se \: va \: scrie \times \frac{5}{6}$

Prin urmare:

$\frac{77}{50} \times \frac{19}{16} \times \frac{5}{6}$

$= \frac{7315}{4800}$

Se simplifica cu 5 si se obtine

$\frac{1463}{960}$
