Question

X/y = 2/7 x+y/y= va rog rapid

Answer 1

$\frac{x}{y} = \frac{2}{7} =k \\ \\ x=2k \\ \\ y=7k \\ \\ \frac{x+y}{y} = \frac{2k+7k}{7k} = \frac{9k}{7k} = \frac{9}{7}$

Answer 2

x / y = 2 / 7 = K

x / 2 =  K => x  = 2 K

y / 7 = K  => y = 7 K
 
x + y / y

⇒  ( 2 K + 7 K ) / 7 K = 

9 K  / 7 K

⇒  9 / 7
