What is 2.07 percent of 20 - 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 20 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 20 is 100%, so we can write it down as 20=100%.
4. We know, that x is 2.07% of the output value, so we can write it down as x=2.07%.
5. Now we have two simple equations:
1) 20=100%
2) x=2.07%
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:
20/x=100%/2.07%
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for what is 2.07% of 20

20/x=100/2.07
(20/x)*x=(100/2.07)*x       - we multiply both sides of the equation by x
20=48.309178743961*x       - we divide both sides of the equation by (48.309178743961) to get x
20/48.309178743961=x
0.414=x
x=0.414

now we have:
2.07% of 20=0.414
