What is 7.1 percent of 250 - 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 250 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 250 is 100%, so we can write it down as 250=100%.
4. We know, that x is 7.1% of the output value, so we can write it down as x=7.1%.
5. Now we have two simple equations:
1) 250=100%
2) x=7.1%
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:
250/x=100%/7.1%
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 7.1% of 250

250/x=100/7.1
(250/x)*x=(100/7.1)*x       - we multiply both sides of the equation by x
250=14.084507042254*x       - we divide both sides of the equation by (14.084507042254) to get x
250/14.084507042254=x
17.75=x
x=17.75

now we have:
7.1% of 250=17.75
