What is 71.7 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 71.7% of the output value, so we can write it down as x=71.7%.
5. Now we have two simple equations:
1) 850=100%
2) x=71.7%
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%/71.7%
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 71.7% of 850

850/x=100/71.7
(850/x)*x=(100/71.7)*x       - we multiply both sides of the equation by x
850=1.39470013947*x       - we divide both sides of the equation by (1.39470013947) to get x
850/1.39470013947=x
609.45=x
x=609.45

now we have:
71.7% of 850=609.45
