What is 88.5 percent of 634 - 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 634 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 634 is 100%, so we can write it down as 634=100%.
4. We know, that x is 88.5% of the output value, so we can write it down as x=88.5%.
5. Now we have two simple equations:
1) 634=100%
2) x=88.5%
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:
634/x=100%/88.5%
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 88.5% of 634

634/x=100/88.5
(634/x)*x=(100/88.5)*x       - we multiply both sides of the equation by x
634=1.1299435028249*x       - we divide both sides of the equation by (1.1299435028249) to get x
634/1.1299435028249=x
561.09=x
x=561.09

now we have:
88.5% of 634=561.09
