[2,(6)+1,2(6)+11/6]*0,75
=[tex] [\frac{26-2}{9}+ \frac{126-12}{90}]* \frac{75}{100} [/tex]
=[tex]( \frac{24}{9}+ \frac{114}{90})* \frac{75}{100} [/tex]
inmultim prima fractie cu 10..pt ca numitorul comun este 90
si vine:
=[tex] (\frac{240+114}{90} )* \frac{75}{100}[/tex]
=[tex] \frac{354}{90}* \frac{75}{100} [/tex]
=[tex] \frac{26550}{9000} [/tex]
