What is 42.21 percent of 100 - 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 100 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 is 100%, so we can write it down as 100=100%.
4. We know, that x is 42.21% of the output value, so we can write it down as x=42.21%.
5. Now we have two simple equations:
1) 100=100%
2) x=42.21%
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=100%/42.21%
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for what is 42.21% of 100

100/x=100/42.21
(100/x)*x=(100/42.21)*x       - we multiply both sides of the equation by x
100=2.3691068467188*x       - we divide both sides of the equation by (2.3691068467188) to get x
100/2.3691068467188=x
42.21=x
x=42.21

now we have:
42.21% of 100=42.21
