3.15 is what percent of 129.84 - 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 129.84 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 129.84, so we can write it down as 100%=129.84.
4. We know, that x% equals 3.15 of the output value, so we can write it down as x%=3.15.
5. Now we have two simple equations:
1) 100%=129.84
2) x%=3.15
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%=129.84/3.15
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 3.15 is what percent of 129.84

100%/x%=129.84/3.15
(100/x)*x=(129.84/3.15)*x       - we multiply both sides of the equation by x
100=41.219047619048*x       - we divide both sides of the equation by (41.219047619048) to get x
100/41.219047619048=x
2.4260628465804=x
x=2.4260628465804

now we have:
3.15 is 2.4260628465804% of 129.84
