What is 21700 percent of 31700 - 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 31700 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 31700 is 100%, so we can write it down as 31700=100%.
4. We know, that x is 21700% of the output value, so we can write it down as x=21700%.
5. Now we have two simple equations:
1) 31700=100%
2) x=21700%
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:
31700/x=100%/21700%
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 21700% of 31700

31700/x=100/21700
(31700/x)*x=(100/21700)*x       - we multiply both sides of the equation by x
31700=0.0046082949308756*x       - we divide both sides of the equation by (0.0046082949308756) to get x
31700/0.0046082949308756=x
6878900=x
x=6878900

now we have:
21700% of 31700=6878900
