What is 4.02 percent of 30.3 - 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 30.3 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 30.3 is 100%, so we can write it down as 30.3=100%.
4. We know, that x is 4.02% of the output value, so we can write it down as x=4.02%.
5. Now we have two simple equations:
1) 30.3=100%
2) x=4.02%
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:
30.3/x=100%/4.02%
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 4.02% of 30.3

30.3/x=100/4.02
(30.3/x)*x=(100/4.02)*x       - we multiply both sides of the equation by x
30.3=24.875621890547*x       - we divide both sides of the equation by (24.875621890547) to get x
30.3/24.875621890547=x
1.21806=x
x=1.21806

now we have:
4.02% of 30.3=1.21806
