211.5 is what percent of 1178.8 - 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 1178.8 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 1178.8, so we can write it down as 100%=1178.8.
4. We know, that x% equals 211.5 of the output value, so we can write it down as x%=211.5.
5. Now we have two simple equations:
1) 100%=1178.8
2) x%=211.5
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%=1178.8/211.5
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 211.5 is what percent of 1178.8

100%/x%=1178.8/211.5
(100/x)*x=(1178.8/211.5)*x       - we multiply both sides of the equation by x
100=5.5735224586288*x       - we divide both sides of the equation by (5.5735224586288) to get x
100/5.5735224586288=x
17.941974889718=x
x=17.941974889718

now we have:
211.5 is 17.941974889718% of 1178.8
