7.15 is what percent of 319 - 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 319 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 319, so we can write it down as 100%=319.
4. We know, that x% equals 7.15 of the output value, so we can write it down as x%=7.15.
5. Now we have two simple equations:
1) 100%=319
2) x%=7.15
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%=319/7.15
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 7.15 is what percent of 319

100%/x%=319/7.15
(100/x)*x=(319/7.15)*x       - we multiply both sides of the equation by x
100=44.615384615385*x       - we divide both sides of the equation by (44.615384615385) to get x
100/44.615384615385=x
2.2413793103448=x
x=2.2413793103448

now we have:
7.15 is 2.2413793103448% of 319
