What is 3.4 percent of 121998 - 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 121998 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 121998 is 100%, so we can write it down as 121998=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) 121998=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:
121998/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 121998

121998/x=100/3.4
(121998/x)*x=(100/3.4)*x       - we multiply both sides of the equation by x
121998=29.411764705882*x       - we divide both sides of the equation by (29.411764705882) to get x
121998/29.411764705882=x
4147.932=x
x=4147.932

now we have:
3.4% of 121998=4147.932
