Răspuns:
[tex]\frac{222}{35}[/tex]
Explicație pas cu pas:
= [tex]2\frac{1}{10} +1\frac{1}{35} +1\frac{3}{14}[/tex]
= [tex]\frac{21}{10} + \frac{106}{35} + \frac{17}{14}[/tex]
= [tex]\frac{21*7}{10*7} + \frac{106*2}{35*2} +\frac{17*5}{14*5}[/tex]
= [tex]\frac{147}{70}+\frac{212}{70}+\frac{85}{70}[/tex]
= [tex]\frac{444}{70}[/tex]
= [tex]\frac{222}{35}[/tex]
