9.45 is what percent of 1200 - 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 1200 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 1200, so we can write it down as 100%=1200.
4. We know, that x% equals 9.45 of the output value, so we can write it down as x%=9.45.
5. Now we have two simple equations:
1) 100%=1200
2) x%=9.45
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%=1200/9.45
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 9.45 is what percent of 1200

100%/x%=1200/9.45
(100/x)*x=(1200/9.45)*x       - we multiply both sides of the equation by x
100=126.98412698413*x       - we divide both sides of the equation by (126.98412698413) to get x
100/126.98412698413=x
0.7875=x
x=0.7875

now we have:
9.45 is 0.7875% of 1200
