What is 71 percent of 312 - 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 312 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 312 is 100%, so we can write it down as 312=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) 312=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:
312/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 312

312/x=100/71
(312/x)*x=(100/71)*x       - we multiply both sides of the equation by x
312=1.4084507042254*x       - we divide both sides of the equation by (1.4084507042254) to get x
312/1.4084507042254=x
221.52=x
x=221.52

now we have:
71% of 312=221.52
