What is 1.7 percent of 21216 - 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 21216 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 21216 is 100%, so we can write it down as 21216=100%.
4. We know, that x is 1.7% of the output value, so we can write it down as x=1.7%.
5. Now we have two simple equations:
1) 21216=100%
2) x=1.7%
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:
21216/x=100%/1.7%
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 1.7% of 21216

21216/x=100/1.7
(21216/x)*x=(100/1.7)*x       - we multiply both sides of the equation by x
21216=58.823529411765*x       - we divide both sides of the equation by (58.823529411765) to get x
21216/58.823529411765=x
360.672=x
x=360.672

now we have:
1.7% of 21216=360.672
