Question

Rezolvati ecuatia asta pas cu pas va rog  1,(3)+[1,(6)-2]

Answer 1

[tex]1,(3)+[1,(6)-2]= \\ \\ 1 \frac{3}{9}+(1 \frac{6}{9}- \frac{6}{3})= \\ \\ 1 \frac{1}{3}+( 1\frac{2}{3}- \frac{6}{3})= \\ \\ \frac{4}{3}+( \frac{5}{3}- \frac{6}{3})= \\ \\ \frac{4}{3}- \frac{1}{3}= \\ \\ \frac{3}{3}=1 [/tex]

Answer 2

$1,(3)+[1,(6)-2]= \\ \frac{13-1}{9}+( \frac{16-1}{9}-2)= \\ \frac{12}{9}+( \frac{15}{9}-2)= \\ \frac{12}{9}+(\frac{15}{9}- \frac{18}{9} )= \\ \frac{12}{9}+(- \frac{3}{9})= \\ \frac{12}{9}-\frac{3}{9}= \\ \frac{9}{9} = 1$
