What is 842 percent of 8.5 - 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 8.5 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 8.5 is 100%, so we can write it down as 8.5=100%.
4. We know, that x is 842% of the output value, so we can write it down as x=842%.
5. Now we have two simple equations:
1) 8.5=100%
2) x=842%
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:
8.5/x=100%/842%
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 842% of 8.5

8.5/x=100/842
(8.5/x)*x=(100/842)*x       - we multiply both sides of the equation by x
8.5=0.1187648456057*x       - we divide both sides of the equation by (0.1187648456057) to get x
8.5/0.1187648456057=x
71.57=x
x=71.57

now we have:
842% of 8.5=71.57
