What is 1.39 percent of 2.87 - 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 2.87 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 2.87 is 100%, so we can write it down as 2.87=100%.
4. We know, that x is 1.39% of the output value, so we can write it down as x=1.39%.
5. Now we have two simple equations:
1) 2.87=100%
2) x=1.39%
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:
2.87/x=100%/1.39%
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for what is 1.39% of 2.87

2.87/x=100/1.39
(2.87/x)*x=(100/1.39)*x       - we multiply both sides of the equation by x
2.87=71.942446043165*x       - we divide both sides of the equation by (71.942446043165) to get x
2.87/71.942446043165=x
0.039893=x
x=0.039893

now we have:
1.39% of 2.87=0.039893
