6.7 is what percent of 30.4 - 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 30.4 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 30.4, so we can write it down as 100%=30.4.
4. We know, that x% equals 6.7 of the output value, so we can write it down as x%=6.7.
5. Now we have two simple equations:
1) 100%=30.4
2) x%=6.7
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%=30.4/6.7
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 6.7 is what percent of 30.4

100%/x%=30.4/6.7
(100/x)*x=(30.4/6.7)*x       - we multiply both sides of the equation by x
100=4.5373134328358*x       - we divide both sides of the equation by (4.5373134328358) to get x
100/4.5373134328358=x
22.039473684211=x
x=22.039473684211

now we have:
6.7 is 22.039473684211% of 30.4
