2.87 is what percent of 0.07 - 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 0.07 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 0.07, so we can write it down as 100%=0.07.
4. We know, that x% equals 2.87 of the output value, so we can write it down as x%=2.87.
5. Now we have two simple equations:
1) 100%=0.07
2) x%=2.87
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%=0.07/2.87
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 2.87 is what percent of 0.07

100%/x%=0.07/2.87
(100/x)*x=(0.07/2.87)*x       - we multiply both sides of the equation by x
100=0.024390243902439*x       - we divide both sides of the equation by (0.024390243902439) to get x
100/0.024390243902439=x
4100=x
x=4100

now we have:
2.87 is 4100% of 0.07
