4.2 is what percent of 41.1 - 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 41.1 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 41.1, so we can write it down as 100%=41.1.
4. We know, that x% equals 4.2 of the output value, so we can write it down as x%=4.2.
5. Now we have two simple equations:
1) 100%=41.1
2) x%=4.2
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%=41.1/4.2
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 4.2 is what percent of 41.1

100%/x%=41.1/4.2
(100/x)*x=(41.1/4.2)*x       - we multiply both sides of the equation by x
100=9.7857142857143*x       - we divide both sides of the equation by (9.7857142857143) to get x
100/9.7857142857143=x
10.21897810219=x
x=10.21897810219

now we have:
4.2 is 10.21897810219% of 41.1
