What is 2.12 percent of 27.87 - 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 27.87 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 27.87 is 100%, so we can write it down as 27.87=100%.
4. We know, that x is 2.12% of the output value, so we can write it down as x=2.12%.
5. Now we have two simple equations:
1) 27.87=100%
2) x=2.12%
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:
27.87/x=100%/2.12%
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 2.12% of 27.87

27.87/x=100/2.12
(27.87/x)*x=(100/2.12)*x       - we multiply both sides of the equation by x
27.87=47.169811320755*x       - we divide both sides of the equation by (47.169811320755) to get x
27.87/47.169811320755=x
0.590844=x
x=0.590844

now we have:
2.12% of 27.87=0.590844
