What is 21.5 percent of 92 - 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 92 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 92 is 100%, so we can write it down as 92=100%.
4. We know, that x is 21.5% of the output value, so we can write it down as x=21.5%.
5. Now we have two simple equations:
1) 92=100%
2) x=21.5%
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:
92/x=100%/21.5%
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 21.5% of 92

92/x=100/21.5
(92/x)*x=(100/21.5)*x       - we multiply both sides of the equation by x
92=4.6511627907*x       - we divide both sides of the equation by (4.6511627907) to get x
92/4.6511627907=x
19.78=x
x=19.78

now we have:
21.5% of 92=19.78
