What is 47 percent of 851 - 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 851 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 851 is 100%, so we can write it down as 851=100%.
4. We know, that x is 47% of the output value, so we can write it down as x=47%.
5. Now we have two simple equations:
1) 851=100%
2) x=47%
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:
851/x=100%/47%
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 47% of 851

851/x=100/47
(851/x)*x=(100/47)*x       - we multiply both sides of the equation by x
851=2.1276595744681*x       - we divide both sides of the equation by (2.1276595744681) to get x
851/2.1276595744681=x
399.97=x
x=399.97

now we have:
47% of 851=399.97
