What is 39 percent of 4900 - 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 4900 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 4900 is 100%, so we can write it down as 4900=100%.
4. We know, that x is 39% of the output value, so we can write it down as x=39%.
5. Now we have two simple equations:
1) 4900=100%
2) x=39%
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:
4900/x=100%/39%
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 39% of 4900

4900/x=100/39
(4900/x)*x=(100/39)*x       - we multiply both sides of the equation by x
4900=2.5641025641026*x       - we divide both sides of the equation by (2.5641025641026) to get x
4900/2.5641025641026=x
1911=x
x=1911

now we have:
39% of 4900=1911
