30.4 is what percent of 35.8 - 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 35.8 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 35.8, so we can write it down as 100%=35.8.
4. We know, that x% equals 30.4 of the output value, so we can write it down as x%=30.4.
5. Now we have two simple equations:
1) 100%=35.8
2) x%=30.4
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%=35.8/30.4
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 30.4 is what percent of 35.8

100%/x%=35.8/30.4
(100/x)*x=(35.8/30.4)*x       - we multiply both sides of the equation by x
100=1.1776315789474*x       - we divide both sides of the equation by (1.1776315789474) to get x
100/1.1776315789474=x
84.916201117318=x
x=84.916201117318

now we have:
30.4 is 84.916201117318% of 35.8
