Question

A expressao (figura abaixo) é igual a:​

Answer 1

$\frac{\frac{2}{3}+\frac{1}{4}}{1+\frac{3}{8}}~~\rightarrow~~\frac{MMC(numerador)\,=\,12}{MMC(denominador)\,=\,8}\\\\\\\frac{\frac{4~.~2~+~3~.~1}{12}}{\frac{8~.~1~+~1~.~3}{8}}~=~\frac{\frac{11}{12}}{\frac{11}{8}}~=~\frac{11}{12}~.~\frac{8}{11}~=~\frac{8}{12}~=~\boxed{\frac{2}{3}}$
