Question

calculați si scrieți rezultatul sub formă de fracție ireductibilă:(6/10+1/2)*5+1/2:(2/5-1/10)+2

Answer 1

(6+5)5/10 + 1/2 : (4-1)/10 + 2 =

= 11/5 + 1/2 x 10/3 + 2 =

= 11/5 +5/3 +2 =

=(33+15+30)/15 =

=78/15 =5 intregi si 3/15 = 5 intregi si 1/5

Answer 2

$(\frac{6}{10} +$$\frac{1}{2} )*5$ $+\frac{1}{2}$ $:( \frac{2}{5} }$ $- \frac{1}{10})+2=$
$( \frac{6}{10}+$ $\frac{5}{10} )*5$ $+\frac{1}{2}:$ $(\frac{4}{10}-$ $\frac{1}{10})+2 =$
$\frac{11*5}{10}+$ $\frac{1}{2}*$ $\frac{10}{3}+2 =$ $\frac{11}{2}+$$\frac{5}{3}+2=$ $\frac{33}{6}+$ $\frac{10}{6}+$ $\frac{12}{6}=$ $\frac{33+10+12}{6}=$ $\frac{55}{6}$
