5.4 is what percent of 203.8 - 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 203.8 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 203.8, so we can write it down as 100%=203.8.
4. We know, that x% equals 5.4 of the output value, so we can write it down as x%=5.4.
5. Now we have two simple equations:
1) 100%=203.8
2) x%=5.4
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%=203.8/5.4
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 5.4 is what percent of 203.8

100%/x%=203.8/5.4
(100/x)*x=(203.8/5.4)*x       - we multiply both sides of the equation by x
100=37.740740740741*x       - we divide both sides of the equation by (37.740740740741) to get x
100/37.740740740741=x
2.6496565260059=x
x=2.6496565260059

now we have:
5.4 is 2.6496565260059% of 203.8
