Question

alguem consegue resolver isso?​

Answer 1

$\frac{4}{y} = \frac{2}{4} \\ 2y = 16 \\ y = \frac{16}{2} \\ y = 8$

$\frac{x}{4} = \frac{3}{2} \\ 2x = 12 \\ x = \frac{12}{2} \\ x = 6$

$\frac{z}{12} = \frac{4}{y} \\ \\ y = 8 \\ \\ \frac{z}{12} = \frac{4}{8} \\ 8z = 48 \\ z = \frac{48}{8} \\ z = 6$
