What is 1.3 percent of 31497.89 - 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 31497.89 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 31497.89 is 100%, so we can write it down as 31497.89=100%.
4. We know, that x is 1.3% of the output value, so we can write it down as x=1.3%.
5. Now we have two simple equations:
1) 31497.89=100%
2) x=1.3%
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:
31497.89/x=100%/1.3%
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 1.3% of 31497.89

31497.89/x=100/1.3
