42.13 is what percent of 2.128 - 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 2.128 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 2.128, so we can write it down as 100%=2.128.
4. We know, that x% equals 42.13 of the output value, so we can write it down as x%=42.13.
5. Now we have two simple equations:
1) 100%=2.128
2) x%=42.13
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%=2.128/42.13
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 42.13 is what percent of 2.128

100%/x%=2.128/42.13
(100/x)*x=(2.128/42.13)*x       - we multiply both sides of the equation by x
100=0.050510325183954*x       - we divide both sides of the equation by (0.050510325183954) to get x
100/0.050510325183954=x
1979.7932330827=x
x=1979.7932330827

now we have:
42.13 is 1979.7932330827% of 2.128
