6.42 is what 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% equals 100, so we can write it down as 100%=100.
4. We know, that x% equals 6.42 of the output value, so we can write it down as x%=6.42.
5. Now we have two simple equations:
1) 100%=100
2) x%=6.42
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%=100/6.42
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 6.42 is what percent of 100

100%/x%=100/6.42
(100/x)*x=(100/6.42)*x       - we multiply both sides of the equation by x
100=15.576323987539*x       - we divide both sides of the equation by (15.576323987539) to get x
100/15.576323987539=x
6.42=x
x=6.42

now we have:
6.42 is 6.42% of 100
