What is 8.74 percent of 644.99 - 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 644.99 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 644.99 is 100%, so we can write it down as 644.99=100%.
4. We know, that x is 8.74% of the output value, so we can write it down as x=8.74%.
5. Now we have two simple equations:
1) 644.99=100%
2) x=8.74%
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:
644.99/x=100%/8.74%
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 8.74% of 644.99

644.99/x=100/8.74
(644.99/x)*x=(100/8.74)*x       - we multiply both sides of the equation by x
644.99=11.441647597254*x       - we divide both sides of the equation by (11.441647597254) to get x
644.99/11.441647597254=x
56.372126=x
x=56.372126

now we have:
8.74% of 644.99=56.372126
