Verified answer

Resposta:

a) [tex]\frac{57}{18}[/tex]

b) [tex]\frac{27}{486}[/tex]

c) [tex]\frac{180}{72}[/tex]

d)[tex]\frac{164}{224}[/tex]

Explicação passo a passo:

a) [tex]\frac{13}{2} -\frac{11}{3}[/tex] = [tex]\frac{39}{6} -\frac{22}{6}[/tex]= [tex]\frac{17}{6}[/tex]

[tex]\frac{17}{6} +\frac{1}{3}= \frac{51}{18}+ \frac{6}{18}= \frac{57}{18}[/tex]

b)[tex]\frac{5}{18} +\frac{4}{9}= \frac{45}{162} +\frac{72}{162}= \frac{117}{162}[/tex]

[tex]\frac{117}{162} -\frac{2}{3}= \frac{351}{486}- \frac{324}{486} =\frac{27}{486}[/tex]

c)[tex]\frac{1}{2}+ \frac{5}{6}= \frac{6}{12}+ \frac{10}{12}= \frac{16}{12}[/tex]

[tex]\frac{16}{12} +\frac{7}{6} =\frac{96}{72} +\frac{84}{72} =\frac{180}{72}[/tex]

d)[tex]\frac{6}{7} -\frac{3}{8}= \frac{48}{56}- \frac{21}{56} =\frac{27}{56}[/tex]

[tex]\frac{27}{56}+\frac{1}{4}=\frac{108}{224} +\frac{56}{224}=\frac{164}{224}[/tex]
