20.3 is what percent of 2140 - 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 2140 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 2140, so we can write it down as 100%=2140.
4. We know, that x% equals 20.3 of the output value, so we can write it down as x%=20.3.
5. Now we have two simple equations:
1) 100%=2140
2) x%=20.3
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%=2140/20.3
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 20.3 is what percent of 2140

100%/x%=2140/20.3
(100/x)*x=(2140/20.3)*x       - we multiply both sides of the equation by x
100=105.41871921182*x       - we divide both sides of the equation by (105.41871921182) to get x
100/105.41871921182=x
0.94859813084112=x
x=0.94859813084112

now we have:
20.3 is 0.94859813084112% of 2140
