Question

Daca x/y=3 si x/z=1/2, afla valoarea raportului numerelor y si z

Answer 1

Bună!

$\frac{x}{y} =3 => y=\frac{x}{3}$

$\frac{x}{z} =\frac{1}{2} => z=2x$

$\frac{y}{z} =\frac{\frac{x}{3} }{2x} =\frac{x}{3} *\frac{1}{2x} =\frac{x}{6x} =\frac{1}{6}$

Answer 2

Răspuns:

Explicație pas cu pas:

x/y = 3  si  x/z = 1/2

x/z : (x/y) = 1/2 : 3

( x/z) × ( y/x) = (1/2) × ( 1/3)

y/z = 1/6 → valoarea raportului

_______________________________

sau:

x/y = 3 ⇒  y = x/3

x/z = 1/2 ⇒ z = 2 x

______________

y/z = (x/3) : 2 x = (x/3) × ( 1/2x) = ( x/x) × 1/(2×3) = 1/6

x/x = 1
