Solved Example: 

Find the value of x in the proportion 4 : 7 = 28 : x.

Solution:

The given proportion is 4 : 7 = 28 : x

4/7 = 28/X

28/X = 4/7

X/28 = 7/4

X = 7/4 × 28

X = 7 × 7

X = 49

Therefore the other proportion value of x = 49.

Now, try the calculator to find the value of x in each of the following proportions.

  • 2 : 11 = X : 242
  • 4 : 3 = 428 : X
