2.1 is what percent of 2700000 - 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 2700000 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 2700000, so we can write it down as 100%=2700000.
4. We know, that x% equals 2.1 of the output value, so we can write it down as x%=2.1.
5. Now we have two simple equations:
1) 100%=2700000
2) x%=2.1
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%=2700000/2.1
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 2.1 is what percent of 2700000

100%/x%=2700000/2.1
(100/x)*x=(2700000/2.1)*x       - we multiply both sides of the equation by x
100=1285714.2857143*x       - we divide both sides of the equation by (1285714.2857143) to get x
100/1285714.2857143=x
7.7777777777778E-5=x
x=7.7777777777778E-5

now we have:
2.1 is 7.7777777777778E-5% of 2700000
