х*(1 2/3+5/9)=2/3                                                   решите уравнения      

[latex]x(1 \frac{2}{3}+ \frac{5}{9})= \frac{2}{3} \\ x(1 \frac{6}{9}+ \frac{5}{9})= \frac{2}{3} \\ x*1 \frac{11}{9}= \frac{2}{3} \\ \frac{20}{9}x= \frac{2}{3} \\ x= \frac{2}{3}: \frac{20}{9} \\ x= \frac{2}{3}* \frac{9}{20} \\ x= \frac{3}{10} \\ x=0.3 [/latex]

х*(1 2/3+5/9) = 2/3    1 2/3 = 5/3    5/3 + 5/9 = (45+15)/27 =60/27 х*(60/27) = 2/3 x = (2/3):(60/27) x = (2/3)*(27/60) = (2*27)/(3*60) = 9/30 =3/10 = 0,3 x =  0,3
