2.9 is what percent of 331 - 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 331 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 331, so we can write it down as 100%=331.
4. We know, that x% equals 2.9 of the output value, so we can write it down as x%=2.9.
5. Now we have two simple equations:
1) 100%=331
2) x%=2.9
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%=331/2.9
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 2.9 is what percent of 331

100%/x%=331/2.9
(100/x)*x=(331/2.9)*x       - we multiply both sides of the equation by x
100=114.13793103448*x       - we divide both sides of the equation by (114.13793103448) to get x
100/114.13793103448=x
0.8761329305136=x
x=0.8761329305136

now we have:
2.9 is 0.8761329305136% of 331
