Question

determine a razão de A = 1/2 para B = 3/8 ?

Answer 1

 
Emilly,

Uma razão e a relação entre dois números
Então

           $\frac{A}{B} = \frac{ \frac{1}{2} }{ \frac{3}{8} } = \frac{1x8}{2x3} \\ \\ \frac{A}{B} = \frac{4}{3}$

Answer 2

$A= \dfrac{1}{2} ~~~e~~~B= \dfrac{3}{8} \\\\\\ A~~raz\~ao~~de~~A~~para~~B~~sera\´:~~ \dfrac{A}{B}$


$\dfrac{ \dfrac{1}{2} }{ \dfrac{3}{8} } \to~~ \dfrac{1}{2} \times \dfrac{8}{3}\to~~\dfrac{8}{6}\to~~ \boxed{\frac{4}{3}}$
