Explicație pas cu pas:
[tex]\large\bf 1,75 + \{2 \cdot 3+5,75+[3,75 \cdot(1,35-0,35)+2,25]:3\}:13,75=[/tex]
[tex]\large\bf 1,75 + [6+5,75+(3,75 \cdot 1+2,25):3]:13,75=[/tex]
[tex]\large\bf 1,75 + [6+5,75+(3,75+2,25):3]:13,75=[/tex]
[tex]\large\bf 1,75 + (6+5,75+6:3):13,75=[/tex]
[tex]\large\bf 1,75 + (6+5,75+2):13,75=[/tex]
[tex]\large\bf 1,75 + 13,75:13,75=[/tex]
[tex]\large\bf 1,75 + 1=[/tex]
[tex]\color{red}\Large\boxed{\bf 2,75 }[/tex]
