71.9 is what percent of 313.7 - 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 313.7 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 100% equals 313.7, so we can write it down as 100%=313.7.
4. We know, that x% equals 71.9 of the output value, so we can write it down as x%=71.9.
5. Now we have two simple equations:
1) 100%=313.7
2) x%=71.9
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:
100%/x%=313.7/71.9
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 71.9 is what percent of 313.7

100%/x%=313.7/71.9
(100/x)*x=(313.7/71.9)*x       - we multiply both sides of the equation by x
100=4.3630041724618*x       - we divide both sides of the equation by (4.3630041724618) to get x
100/4.3630041724618=x
22.919987248964=x
x=22.919987248964

now we have:
71.9 is 22.919987248964% of 313.7
