5.4 is what percent of 199.6 - 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 199.6 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 199.6, so we can write it down as 100%=199.6.
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%=199.6
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%=199.6/5.4
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 199.6

100%/x%=199.6/5.4
(100/x)*x=(199.6/5.4)*x       - we multiply both sides of the equation by x
100=36.962962962963*x       - we divide both sides of the equation by (36.962962962963) to get x
100/36.962962962963=x
2.7054108216433=x
x=2.7054108216433

now we have:
5.4 is 2.7054108216433% of 199.6
