1.09 is what percent of 2800 - 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 2800 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 2800, so we can write it down as 100%=2800.
4. We know, that x% equals 1.09 of the output value, so we can write it down as x%=1.09.
5. Now we have two simple equations:
1) 100%=2800
2) x%=1.09
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%=2800/1.09
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 1.09 is what percent of 2800

100%/x%=2800/1.09
(100/x)*x=(2800/1.09)*x       - we multiply both sides of the equation by x
100=2568.8073394495*x       - we divide both sides of the equation by (2568.8073394495) to get x
100/2568.8073394495=x
0.038928571428571=x
x=0.038928571428571

now we have:
1.09 is 0.038928571428571% of 2800
