74 is what percent of 542 - 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 542 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 542, so we can write it down as 100%=542.
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%=542
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%=542/74
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 542

100%/x%=542/74
(100/x)*x=(542/74)*x       - we multiply both sides of the equation by x
100=7.3243243243243*x       - we divide both sides of the equation by (7.3243243243243) to get x
100/7.3243243243243=x
13.653136531365=x
x=13.653136531365

now we have:
74 is 13.653136531365% of 542
