What is 3.45 percent of 1.8 - 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 1.8 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 1.8 is 100%, so we can write it down as 1.8=100%.
4. We know, that x is 3.45% of the output value, so we can write it down as x=3.45%.
5. Now we have two simple equations:
1) 1.8=100%
2) x=3.45%
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:
1.8/x=100%/3.45%
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 3.45% of 1.8

1.8/x=100/3.45
(1.8/x)*x=(100/3.45)*x       - we multiply both sides of the equation by x
1.8=28.985507246377*x       - we divide both sides of the equation by (28.985507246377) to get x
1.8/28.985507246377=x
0.0621=x
x=0.0621

now we have:
3.45% of 1.8=0.0621
