How to solve 2/3:x::4.5:2 and 2/3%:1/5::50:x

A) x = 0.296

B) x = 15

Step-by-step explanation:

Step 1:

(2/3) : x : : 4.5 : 2

By using expansion method,

(2/3) * 2 = 4.5 x

x = (2/3) * 2 / 4.5

x = 0.296

Step 2:

(2/3) : (1/5) : : 50 : x

By using expansion method,

(2/3) x = (1/5) * 50

x = (1/5) * 50 / (2/3)

x = 15
