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

Answer 1

A) x = 0.296

B) x= 15

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
