21.93 is what percent of 637.5 - 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 637.5 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 637.5, so we can write it down as 100%=637.5.
4. We know, that x% equals 21.93 of the output value, so we can write it down as x%=21.93.
5. Now we have two simple equations:
1) 100%=637.5
2) x%=21.93
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%=637.5/21.93
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 21.93 is what percent of 637.5

100%/x%=637.5/21.93
(100/x)*x=(637.5/21.93)*x       - we multiply both sides of the equation by x
100=29.06976744186*x       - we divide both sides of the equation by (29.06976744186) to get x
100/29.06976744186=x
3.44=x
x=3.44

now we have:
21.93 is 3.44% of 637.5
