Question

cum fac exercitiul asta x/2/1/3=1/2/9

Answer 1

$\frac{ \frac{x}{2} }{ \frac{1}{3} } = \frac{ \frac{1}{2} }{9}$

$\frac{x}{2} \times 3 = \frac{1}{2} \times \frac{1}{9}$

$\frac{x \times 3}{2} = \frac{1 \times 1}{2 \times 9}$

$\frac{3x}{2} = \frac{1}{18}$

$3x \times 18 = 2$

$3x = \frac{2}{18}$

$3x = \frac{1}{9}$

$3x \times 9 = 1$

$27x = 1$

$x = \frac{1}{27}$
