What is 685 percent of 830 - 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 830 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 830 is 100%, so we can write it down as 830=100%.
4. We know, that x is 685% of the output value, so we can write it down as x=685%.
5. Now we have two simple equations:
1) 830=100%
2) x=685%
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:
830/x=100%/685%
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 685% of 830

830/x=100/685
(830/x)*x=(100/685)*x       - we multiply both sides of the equation by x
830=0.14598540145985*x       - we divide both sides of the equation by (0.14598540145985) to get x
830/0.14598540145985=x
5685.5=x
x=5685.5

now we have:
685% of 830=5685.5
