What is 15.5 percent of 858.17 - 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 858.17 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 858.17 is 100%, so we can write it down as 858.17=100%.
4. We know, that x is 15.5% of the output value, so we can write it down as x=15.5%.
5. Now we have two simple equations:
1) 858.17=100%
2) x=15.5%
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:
858.17/x=100%/15.5%
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 15.5% of 858.17

858.17/x=100/15.5
(858.17/x)*x=(100/15.5)*x       - we multiply both sides of the equation by x
858.17=6.4516129032258*x       - we divide both sides of the equation by (6.4516129032258) to get x
858.17/6.4516129032258=x
133.01635=x
x=133.01635

now we have:
15.5% of 858.17=133.01635
