What is 78.4 percent of 490000 - 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 490000 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 490000 is 100%, so we can write it down as 490000=100%.
4. We know, that x is 78.4% of the output value, so we can write it down as x=78.4%.
5. Now we have two simple equations:
1) 490000=100%
2) x=78.4%
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:
490000/x=100%/78.4%
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 78.4% of 490000

490000/x=100/78.4
(490000/x)*x=(100/78.4)*x       - we multiply both sides of the equation by x
490000=1.2755102040816*x       - we divide both sides of the equation by (1.2755102040816) to get x
490000/1.2755102040816=x
384160=x
x=384160

now we have:
78.4% of 490000=384160
