53.4 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 53.4 of the output value, so we can write it down as x%=53.4.
5. Now we have two simple equations:
1) 100%=74
2) x%=53.4
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%=74/53.4
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 53.4 is what percent of 74

100%/x%=74/53.4
(100/x)*x=(74/53.4)*x       - we multiply both sides of the equation by x
100=1.3857677902622*x       - we divide both sides of the equation by (1.3857677902622) to get x
100/1.3857677902622=x
72.162162162162=x
x=72.162162162162

now we have:
53.4 is 72.162162162162% of 74
