20 is what percent of 273.3 - 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 273.3 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 273.3, so we can write it down as 100%=273.3.
4. We know, that x% equals 20 of the output value, so we can write it down as x%=20.
5. Now we have two simple equations:
1) 100%=273.3
2) x%=20
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%=273.3/20
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 20 is what percent of 273.3

100%/x%=273.3/20
(100/x)*x=(273.3/20)*x       - we multiply both sides of the equation by x
100=13.665*x       - we divide both sides of the equation by (13.665) to get x
100/13.665=x
7.3179656055617=x
x=7.3179656055617

now we have:
20 is 7.3179656055617% of 273.3
