What is 6.87 percent of 21.04 - 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 21.04 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 21.04 is 100%, so we can write it down as 21.04=100%.
4. We know, that x is 6.87% of the output value, so we can write it down as x=6.87%.
5. Now we have two simple equations:
1) 21.04=100%
2) x=6.87%
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:
21.04/x=100%/6.87%
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 6.87% of 21.04

21.04/x=100/6.87
(21.04/x)*x=(100/6.87)*x       - we multiply both sides of the equation by x
21.04=14.556040756914*x       - we divide both sides of the equation by (14.556040756914) to get x
21.04/14.556040756914=x
1.445448=x
x=1.445448

now we have:
6.87% of 21.04=1.445448
