187.2 is what percent of 618 - 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 618 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 618, so we can write it down as 100%=618.
4. We know, that x% equals 187.2 of the output value, so we can write it down as x%=187.2.
5. Now we have two simple equations:
1) 100%=618
2) x%=187.2
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%=618/187.2
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 187.2 is what percent of 618

100%/x%=618/187.2
(100/x)*x=(618/187.2)*x       - we multiply both sides of the equation by x
100=3.3012820512821*x       - we divide both sides of the equation by (3.3012820512821) to get x
100/3.3012820512821=x
30.291262135922=x
x=30.291262135922

now we have:
187.2 is 30.291262135922% of 618
