74 is what percent of 406 - 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 406 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 406, so we can write it down as 100%=406.
4. We know, that x% equals 74 of the output value, so we can write it down as x%=74.
5. Now we have two simple equations:
1) 100%=406
2) x%=74
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%=406/74
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 74 is what percent of 406

100%/x%=406/74
(100/x)*x=(406/74)*x       - we multiply both sides of the equation by x
100=5.4864864864865*x       - we divide both sides of the equation by (5.4864864864865) to get x
100/5.4864864864865=x
18.226600985222=x
x=18.226600985222

now we have:
74 is 18.226600985222% of 406
