Answer 1

Answer:

Step-by-step explanation:

1. 2:x = 1:2

=> 2 / x = 1 / 2

=> x / 2 = 2

=> x = 2 * 2

=> x = 4 --- (i)

2. x:y = 2:3

From eq. (i)

x = 4

=> 4:y = 2:3

=> 4 / y = 2 / 3

=> y / 4 = 3 /2

=> y = 3 /2 * 4

=> y = 3 * 2

=> y = 6

Therefore, x = 4 , y = 6

Answer 2

Answer:

$x = 4$, $y = 6$

Step-by-step explanation:

Given that,

x:y = 2:3

∴ $\frac{x}{y} = \frac{2}{3}$

∴ $3x = 2y$   . . . . . . . . . . . . . . .  (i)

Also, given that,

2:x = 1:2

∴ $\frac{2}{x} = \frac{1}{2}$

∴ $x = (2).(2) = 4$  

Putting value of x into equation (i):

$(3).(4) = 2y$

∴ $2y = (3).(4) = 12$

∴ $y = 6$
