2.17 is what percent of 43.5 - 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 43.5 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 43.5, so we can write it down as 100%=43.5.
4. We know, that x% equals 2.17 of the output value, so we can write it down as x%=2.17.
5. Now we have two simple equations:
1) 100%=43.5
2) x%=2.17
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%=43.5/2.17
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 2.17 is what percent of 43.5

100%/x%=43.5/2.17
(100/x)*x=(43.5/2.17)*x       - we multiply both sides of the equation by x
100=20.046082949309*x       - we divide both sides of the equation by (20.046082949309) to get x
100/20.046082949309=x
4.9885057471264=x
x=4.9885057471264

now we have:
2.17 is 4.9885057471264% of 43.5
