2.15 is what percent of 10.97 - 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 10.97 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 10.97, so we can write it down as 100%=10.97.
4. We know, that x% equals 2.15 of the output value, so we can write it down as x%=2.15.
5. Now we have two simple equations:
1) 100%=10.97
2) x%=2.15
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%=10.97/2.15
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 2.15 is what percent of 10.97

100%/x%=10.97/2.15
(100/x)*x=(10.97/2.15)*x       - we multiply both sides of the equation by x
100=5.1023255813953*x       - we divide both sides of the equation by (5.1023255813953) to get x
100/5.1023255813953=x
19.598906107566=x
x=19.598906107566

now we have:
2.15 is 19.598906107566% of 10.97
