98.8 is what percent of 438.12 - 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 438.12 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 438.12, so we can write it down as 100%=438.12.
4. We know, that x% equals 98.8 of the output value, so we can write it down as x%=98.8.
5. Now we have two simple equations:
1) 100%=438.12
2) x%=98.8
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%=438.12/98.8
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 98.8 is what percent of 438.12

100%/x%=438.12/98.8
(100/x)*x=(438.12/98.8)*x       - we multiply both sides of the equation by x
100=4.4344129554656*x       - we divide both sides of the equation by (4.4344129554656) to get x
100/4.4344129554656=x
22.550899296996=x
x=22.550899296996

now we have:
98.8 is 22.550899296996% of 438.12
