What is 3.21 percent of 67.45 - 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 67.45 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 67.45 is 100%, so we can write it down as 67.45=100%.
4. We know, that x is 3.21% of the output value, so we can write it down as x=3.21%.
5. Now we have two simple equations:
1) 67.45=100%
2) x=3.21%
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:
67.45/x=100%/3.21%
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 3.21% of 67.45

67.45/x=100/3.21
(67.45/x)*x=(100/3.21)*x       - we multiply both sides of the equation by x
67.45=31.152647975078*x       - we divide both sides of the equation by (31.152647975078) to get x
67.45/31.152647975078=x
2.165145=x
x=2.165145

now we have:
3.21% of 67.45=2.165145
