Question

2,5(7):6,(4)-0,15 este intrebarea mea.

Answer 1

Răspuns:

$\frac{12}{29}$

Explicație pas cu pas:

$\frac{257 - 25}{90} : \frac{64-6}{9} - \frac{15}{100}$

$= \frac{232}{90} * \frac{9}{58} - \frac{3}{20}$

$= \frac{232}{580} - \frac{3}{20}$

$= \frac{232 - 3*29}{580} = \frac{232-87}{580} = \frac{240}{580} = \frac{24}{58} = \frac{12}{29}$
