Question

3/4 + 3/4 + 3/4 + 3/4 = 9 x ?

Answer 1

Resposta:

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

Explicação passo a passo:

$\frac{3}{4}+\frac{3}{4}+\frac{3}{4}+\frac{3}{4}=9x$

$9x=\frac{3}{4}+\frac{3}{4}+\frac{3}{4}+\frac{3}{4}$

$9x=\frac{3+3+3+3}{4}$

$9x=\frac{12}{4}$

$9x=3$

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

Answer 2

3/4 + 3/4 + 3/4 + 3/4 = 9 x
6/4 + 6/4 = 9x
12/4= 9x
3 = 9x
9x = 3
x = 3/9 (:3)/(:3)
X = 1/3
