What is 71 percent of 315 - 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 315 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 315 is 100%, so we can write it down as 315=100%.
4. We know, that x is 71% of the output value, so we can write it down as x=71%.
5. Now we have two simple equations:
1) 315=100%
2) x=71%
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:
315/x=100%/71%
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% of 315

315/x=100/71
(315/x)*x=(100/71)*x       - we multiply both sides of the equation by x
315=1.4084507042254*x       - we divide both sides of the equation by (1.4084507042254) to get x
315/1.4084507042254=x
223.65=x
x=223.65

now we have:
71% of 315=223.65
