What is 850 percent of 428 - 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 428 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 428 is 100%, so we can write it down as 428=100%.
4. We know, that x is 850% of the output value, so we can write it down as x=850%.
5. Now we have two simple equations:
1) 428=100%
2) x=850%
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:
428/x=100%/850%
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 850% of 428

428/x=100/850
(428/x)*x=(100/850)*x       - we multiply both sides of the equation by x
428=0.11764705882353*x       - we divide both sides of the equation by (0.11764705882353) to get x
428/0.11764705882353=x
3638=x
x=3638

now we have:
850% of 428=3638
