2.8 is what percent of 2900 - 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 2900 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 2900, so we can write it down as 100%=2900.
4. We know, that x% equals 2.8 of the output value, so we can write it down as x%=2.8.
5. Now we have two simple equations:
1) 100%=2900
2) x%=2.8
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%=2900/2.8
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 2.8 is what percent of 2900

100%/x%=2900/2.8
(100/x)*x=(2900/2.8)*x       - we multiply both sides of the equation by x
100=1035.7142857143*x       - we divide both sides of the equation by (1035.7142857143) to get x
100/1035.7142857143=x
0.096551724137931=x
x=0.096551724137931

now we have:
2.8 is 0.096551724137931% of 2900
