Question

qual o valor de x nas proporções x/1/3+1=1/4/1-1/3

Answer 1

Oiiii

$\frac{ \frac{x}{1} }{3+1} = \frac{ \frac{1}{4} }{ 1\frac{-1}{3} }$

$\frac{ x}{4} = \frac{ \frac{1}{4} }{ 1\frac{-1}{3} }$

$\frac{ x}{4} = \frac{ \frac{1}{4} }{ \frac{2}{3} }$

$\frac{ x}{4} = \frac{1}{4} . \frac{3}{2}$

$\frac{ x}{4} = \frac{3}{8}$

$8x = 3.4$

$8x = 12$

$x = \frac{12^{:4}}{8^{:4}} = \boxed{ \frac{3}{2} }$
