74.85 is what percent of 424.15 - 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 424.15 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 424.15, so we can write it down as 100%=424.15.
4. We know, that x% equals 74.85 of the output value, so we can write it down as x%=74.85.
5. Now we have two simple equations:
1) 100%=424.15
2) x%=74.85
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%=424.15/74.85
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 74.85 is what percent of 424.15

100%/x%=424.15/74.85
(100/x)*x=(424.15/74.85)*x       - we multiply both sides of the equation by x
100=5.6666666666667*x       - we divide both sides of the equation by (5.6666666666667) to get x
100/5.6666666666667=x
17.647058823529=x
x=17.647058823529

now we have:
74.85 is 17.647058823529% of 424.15
