Explicação passo-a-passo:
[tex]\mathsf{\dfrac{1}{2} + \dfrac{1}{4} + \dfrac{1}{10}}[/tex]
[tex]\mathsf{\dfrac{1}{2/20} + \dfrac{1}{4/20} + \dfrac{1}{10/20}}\leftarrow\textsf{MMC(2, 4, 10) = 20 }[/tex]
[tex]\mathsf{\dfrac{1\times 10}{20} + \dfrac{1\times 5}{20} + \dfrac{1\times 2}{20}}[/tex]
[tex]\mathsf{\dfrac{10}{20} + \dfrac{5}{20} + \dfrac{2}{20}}[/tex]
[tex]\mathsf{\dfrac{10 + 5 + 2}{20}}[/tex]
[tex]\boxed{\boxed{\mathsf{\dfrac{1}{2} + \dfrac{1}{4} + \dfrac{1}{10} = \boxed{\boxed{\dfrac{17}{20}}}}}}[/tex]
