Question

if X + y by X + y + z is equals to y + z by X + y + z is equals to X + z by X + y + z is equal to p then p is equals to​

Answer 1

$p = \frac{x + y}{x + y + z} = \frac{y + z}{x + y + z} = \frac{x + z}{x + y + z}$

$p = \frac{sum \: of \: numerators \: }{sum \: of \: denominators}$

$p = \frac{2(x + y + z)}{3(x + y + z)}$

$p = \frac{2}{3}$
