Repede va rog!.

Answer 1

$[3,(6) + 1,5] : [1,(6)+ \frac{2}{5} ] =$

$(3 \frac{6}{9} + \frac{15}{10} ): (1 \frac{6}{9} + \frac{2}{5} ) =$

$( \frac{3 \times 9 + 6}{9} + \frac{3}{2} ) : (\frac{1 \times 9 + 6}{9} + \frac{2}{5} )=$

$( \frac{33}{9} + \frac{3}{2} ) : (\frac{15}{9} + \frac{2}{5} )=$

$( \frac{11}{3} + \frac{3}{2} ) : (\frac{5}{3} + \frac{2}{5} )=$

$( \frac{22}{6} + \frac{9}{6} ) : (\frac{25}{15} + \frac{6}{15} )=$

$\frac{22 + 9}{6} \div \frac{25 + 6}{15} =$

$\frac{31}{6} \div \frac{31}{15} =$

$\frac{31}{6} \times \frac{15}{31} =$

$= \frac{5}{2}$
