4.1 is what percent of 4.2 - 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 4.2 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 4.2, so we can write it down as 100%=4.2.
4. We know, that x% equals 4.1 of the output value, so we can write it down as x%=4.1.
5. Now we have two simple equations:
1) 100%=4.2
2) x%=4.1
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%=4.2/4.1
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 4.1 is what percent of 4.2

100%/x%=4.2/4.1
(100/x)*x=(4.2/4.1)*x       - we multiply both sides of the equation by x
100=1.0243902439024*x       - we divide both sides of the equation by (1.0243902439024) to get x
100/1.0243902439024=x
97.619047619048=x
x=97.619047619048

now we have:
4.1 is 97.619047619048% of 4.2
