2.15 is what percent of 4.34 - 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 4.34 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 4.34, so we can write it down as 100%=4.34.
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%=4.34
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%=4.34/2.15
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 4.34

100%/x%=4.34/2.15
(100/x)*x=(4.34/2.15)*x       - we multiply both sides of the equation by x
100=2.0186046511628*x       - we divide both sides of the equation by (2.0186046511628) to get x
100/2.0186046511628=x
49.539170506912=x
x=49.539170506912

now we have:
2.15 is 49.539170506912% of 4.34
