Question

$\frac{2x}{15} = \frac{6}{9}$
​

Answer 1

Resposta:

Só multiplicar cruzado

$\frac{2x}{15} = \frac{6}{9}$

2x . 9 = 6 . 15

18x = 90

x = $\frac{90}{18}$

x = 5

Answer 2

Resposta:

x=5

Explicação passo-a-passo:

$\displaystyle \frac{2x}{15} = \frac{6}{9}\\\\\\x=\frac{6}{2}. \frac{15}{9} =3.\frac{15\div3}{9\div3}=\diagup\!\!\!\!3.\frac{5}{\diagup\!\!\!\!3} =5$
