2981.91 is what percent of 4240 - 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 4240 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 4240, so we can write it down as 100%=4240.
4. We know, that x% equals 2981.91 of the output value, so we can write it down as x%=2981.91.
5. Now we have two simple equations:
1) 100%=4240
2) x%=2981.91
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%=4240/2981.91
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 2981.91 is what percent of 4240

100%/x%=4240/2981.91
(100/x)*x=(4240/2981.91)*x       - we multiply both sides of the equation by x
100=1.4219074351674*x       - we divide both sides of the equation by (1.4219074351674) to get x
100/1.4219074351674=x
70.328066037736=x
x=70.328066037736

now we have:
2981.91 is 70.328066037736% of 4240
