2.17 is what percent of 5.42 - 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 5.42 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 5.42, so we can write it down as 100%=5.42.
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%=5.42
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%=5.42/2.17
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 5.42

100%/x%=5.42/2.17
(100/x)*x=(5.42/2.17)*x       - we multiply both sides of the equation by x
100=2.4976958525346*x       - we divide both sides of the equation by (2.4976958525346) to get x
100/2.4976958525346=x
40.036900369004=x
x=40.036900369004

now we have:
2.17 is 40.036900369004% of 5.42
