Como resolver a fração 3/4+7/3-1/1

Answer 1

Boa tarde!

$\tt \dfrac{3}{4} + \dfrac{7}{3} - \dfrac{1}{1}$

$\tt \Longrightarrow \dfrac{ \blue{3.}3 + \red{4.}7}{ \blue{3}. \red{4}} - \dfrac{1}{1}$

$\tt \Longrightarrow \dfrac{9 + 28}{12} - \dfrac{1}{1}$

$\tt \Longrightarrow \dfrac{37}{12} - \dfrac{1}{1}$

$\tt \Longrightarrow \dfrac{ \red{1}.37 - 1. \blue{12}}{ \blue{12}. \red{1} }$

$\tt \Longrightarrow \dfrac{37 - 12}{12}$

$\tt \Longrightarrow \tt \dfrac{25}{12}$
