Process to find Fourth number in ratio when three numbers are Available, Proportions are Equal

Ratio is nothing but the relative size of two or more objects. It can be expressed in many ways. Here, we are offering you the simple process to evaluate the fourth number in the ratio when three numbers are given and their proportions are equal.

  • Take four numbers as a, b, c, d.
  • Let us take a, b, c values are given and want to compute d value.
  • Then the equation will be a: b = c: d.
  • d= b*c/a
  • Substitute the values in the above formula to get the d value.

Examples

Question1: What is the ratio of 240, 180, 120, 540?

Solution:

Given that

240: 180: 120: 540

The first common multiple is 10.

So, divide all the values by 10

240/10: 180/10: 120/10: 540/10

=24:18:12:54

Divide all values by 6

=24/6: 18/6: 12/6: 54/6

=4:3:2:9

240: 180: 120: 540 = 4: 3: 2: 9

Question2: Solve the given ratio and find x value 4:3=8:x?

Solution:

Given that

4:3 = 8:x

The formula to find x value is

x=b*c/a

In the given data a=4, b=3, c=8

Replace the above values in the formula

x= 3*8/4

=3*2

x= 6
