Calculeaza :
3/19 ori 3/4 + 1/5 : 19/3 - 3/19 : 5/2

Answer 1

$\frac{3}{19} * \frac{3}{4} + \frac{1}{5} : \frac{19}{3} - \frac{3}{19} : \frac{5}{2} = \frac{9}{76} + \frac{1}{5} * \frac{3}{19} - \frac{3}{19} * \frac{2}{5} = \\ = \frac{9}{76} + \frac{3}{95} - \frac{6}{95} = \frac{9}{76} - \frac{3}{95} = \frac{45}{380} - \frac{12}{380} = \frac{33}{380}$
