Answer 1

Răspuns:

[ $\frac{3}{5} + \frac{7}{15}$ : ( $\frac{3}{2} - \frac{4}{5}$ )] x $\frac{3}{19}$=

[ $\frac{3}{5} + \frac{7}{15}$ : ($\frac{3*5- 4*2}{10}$)] x$\frac{3}{19}$=

( $\frac{3}{5} + \frac{7}{15}$ : $\frac{7}{10}$) x $\frac{3}{19}$=

($\frac{3}{5} + \frac{7}{15}$ x $\frac{10}{7}$)  x $\frac{3}{19}$=

( $\frac{3}{5} + \frac{2}{3}$ )  x$\frac{3}{19}$ =

$\frac{3*3+2*5}{3*5}$ x$\frac{3}{19}$=

$\frac{9+10}{15}$ x $\frac{3}{19}$= $\frac{19}{15}$ x  $\frac{3}{19}$= $\frac{1}{5}$
