2.85 is what percent of 42.71 - 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 42.71 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 42.71, so we can write it down as 100%=42.71.
4. We know, that x% equals 2.85 of the output value, so we can write it down as x%=2.85.
5. Now we have two simple equations:
1) 100%=42.71
2) x%=2.85
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%=42.71/2.85
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 2.85 is what percent of 42.71

100%/x%=42.71/2.85
(100/x)*x=(42.71/2.85)*x       - we multiply both sides of the equation by x
100=14.985964912281*x       - we divide both sides of the equation by (14.985964912281) to get x
100/14.985964912281=x
6.6729103254507=x
x=6.6729103254507

now we have:
2.85 is 6.6729103254507% of 42.71
