15.1 is what percent of 74 - 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 74 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 74, so we can write it down as 100%=74.
4. We know, that x% equals 15.1 of the output value, so we can write it down as x%=15.1.
5. Now we have two simple equations:
1) 100%=74
2) x%=15.1
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%=74/15.1
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 15.1 is what percent of 74

100%/x%=74/15.1
(100/x)*x=(74/15.1)*x       - we multiply both sides of the equation by x
100=4.9006622516556*x       - we divide both sides of the equation by (4.9006622516556) to get x
100/4.9006622516556=x
20.405405405405=x
x=20.405405405405

now we have:
15.1 is 20.405405405405% of 74
