6.6 is what percent of 15.42 - 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 15.42 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 15.42, so we can write it down as 100%=15.42.
4. We know, that x% equals 6.6 of the output value, so we can write it down as x%=6.6.
5. Now we have two simple equations:
1) 100%=15.42
2) x%=6.6
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%=15.42/6.6
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 6.6 is what percent of 15.42

100%/x%=15.42/6.6
(100/x)*x=(15.42/6.6)*x       - we multiply both sides of the equation by x
100=2.3363636363636*x       - we divide both sides of the equation by (2.3363636363636) to get x
100/2.3363636363636=x
42.801556420233=x
x=42.801556420233

now we have:
6.6 is 42.801556420233% of 15.42
