311.5 is what percent of 1197 - 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 1197 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 1197, so we can write it down as 100%=1197.
4. We know, that x% equals 311.5 of the output value, so we can write it down as x%=311.5.
5. Now we have two simple equations:
1) 100%=1197
2) x%=311.5
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%=1197/311.5
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 311.5 is what percent of 1197

100%/x%=1197/311.5
(100/x)*x=(1197/311.5)*x       - we multiply both sides of the equation by x
100=3.8426966292135*x       - we divide both sides of the equation by (3.8426966292135) to get x
100/3.8426966292135=x
26.023391812865=x
x=26.023391812865

now we have:
311.5 is 26.023391812865% of 1197
