What is 17.8 percent of 850 - 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 850 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 850 is 100%, so we can write it down as 850=100%.
4. We know, that x is 17.8% of the output value, so we can write it down as x=17.8%.
5. Now we have two simple equations:
1) 850=100%
2) x=17.8%
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:
850/x=100%/17.8%
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 17.8% of 850

850/x=100/17.8
(850/x)*x=(100/17.8)*x       - we multiply both sides of the equation by x
850=5.6179775280899*x       - we divide both sides of the equation by (5.6179775280899) to get x
850/5.6179775280899=x
151.3=x
x=151.3

now we have:
17.8% of 850=151.3
