2.172 is what percent of 3 - step by step solution

To get the solution, we are looking for, we need to point out what we know.

1. We assume, that the number 3 is 100% - because it's the output value of the task.
2. We assume, that x is the value we are looking for.
3. If 100% equals 3, so we can write it down as 100%=3.
4. We know, that x% equals 2.172 of the output value, so we can write it down as x%=2.172.
5. Now we have two simple equations:
1) 100%=3
2) x%=2.172
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
100%/x%=3/2.172
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 2.172 is what percent of 3

100%/x%=3/2.172
(100/x)*x=(3/2.172)*x       - we multiply both sides of the equation by x
100=1.3812154696133*x       - we divide both sides of the equation by (1.3812154696133) to get x
100/1.3812154696133=x
72.4=x
x=72.4

now we have:
2.172 is 72.4% of 3
