What is 3.4 percent of 4210 - 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 4210 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 4210 is 100%, so we can write it down as 4210=100%.
4. We know, that x is 3.4% of the output value, so we can write it down as x=3.4%.
5. Now we have two simple equations:
1) 4210=100%
2) x=3.4%
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:
4210/x=100%/3.4%
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 3.4% of 4210

4210/x=100/3.4
(4210/x)*x=(100/3.4)*x       - we multiply both sides of the equation by x
4210=29.411764705882*x       - we divide both sides of the equation by (29.411764705882) to get x
4210/29.411764705882=x
143.14=x
x=143.14

now we have:
3.4% of 4210=143.14
