Question

[3/2-0,(6)] : ( 1/2+1/3-1/4+1/5)

Answer 1

     
$[\frac{3}{2}-0,(6)]:( \frac{1}{2}+\frac{1}{3} +\frac{1}{4}+\frac{1}{5})= \\ \\ =[\frac{3}{2}-\frac{6}{9}]:( \frac{30}{60}+\frac{20}{60} +\frac{15}{60}+\frac{12}{60})= \\ \\ =[\frac{3}{2}-\frac{2}{3}]:( \frac{30+20+15+12}{60})= \\ \\ =[\frac{9}{6}-\frac{4}{6}]:\frac{77}{60}= \\ \\ =\frac{5}{6} *\frac{60}{77}= \\ \\ \frac{5 * 10}{77}= \frac{50}{77}$
