What is 3700 percent of 3900 - 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 3900 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 3900 is 100%, so we can write it down as 3900=100%.
4. We know, that x is 3700% of the output value, so we can write it down as x=3700%.
5. Now we have two simple equations:
1) 3900=100%
2) x=3700%
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:
3900/x=100%/3700%
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 3700% of 3900

3900/x=100/3700
(3900/x)*x=(100/3700)*x       - we multiply both sides of the equation by x
3900=0.027027027027027*x       - we divide both sides of the equation by (0.027027027027027) to get x
3900/0.027027027027027=x
144300=x
x=144300

now we have:
3700% of 3900=144300
