What is 21.56 percent of 2.9 - 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 2.9 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 2.9 is 100%, so we can write it down as 2.9=100%.
4. We know, that x is 21.56% of the output value, so we can write it down as x=21.56%.
5. Now we have two simple equations:
1) 2.9=100%
2) x=21.56%
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:
2.9/x=100%/21.56%
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 21.56% of 2.9

2.9/x=100/21.56
(2.9/x)*x=(100/21.56)*x       - we multiply both sides of the equation by x
2.9=4.6382189239332*x       - we divide both sides of the equation by (4.6382189239332) to get x
2.9/4.6382189239332=x
0.62524=x
x=0.62524

now we have:
21.56% of 2.9=0.62524
