313.2 is what percent of 1111.2 - 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 1111.2 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 1111.2, so we can write it down as 100%=1111.2.
4. We know, that x% equals 313.2 of the output value, so we can write it down as x%=313.2.
5. Now we have two simple equations:
1) 100%=1111.2
2) x%=313.2
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%=1111.2/313.2
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 313.2 is what percent of 1111.2

100%/x%=1111.2/313.2
(100/x)*x=(1111.2/313.2)*x       - we multiply both sides of the equation by x
100=3.5478927203065*x       - we divide both sides of the equation by (3.5478927203065) to get x
100/3.5478927203065=x
28.185745140389=x
x=28.185745140389

now we have:
313.2 is 28.185745140389% of 1111.2
