103.31 is what percent of 640.32 - 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 640.32 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 100% equals 640.32, so we can write it down as 100%=640.32.
4. We know, that x% equals 103.31 of the output value, so we can write it down as x%=103.31.
5. Now we have two simple equations:
1) 100%=640.32
2) x%=103.31
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:
100%/x%=640.32/103.31
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 103.31 is what percent of 640.32

100%/x%=640.32/103.31
(100/x)*x=(640.32/103.31)*x       - we multiply both sides of the equation by x
100=6.1980447197754*x       - we divide both sides of the equation by (6.1980447197754) to get x
100/6.1980447197754=x
16.13412043978=x
x=16.13412043978

now we have:
103.31 is 16.13412043978% of 640.32
