21 is what percent of 6000000 - 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 6000000 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 6000000, so we can write it down as 100%=6000000.
4. We know, that x% equals 21 of the output value, so we can write it down as x%=21.
5. Now we have two simple equations:
1) 100%=6000000
2) x%=21
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%=6000000/21
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 21 is what percent of 6000000

100%/x%=6000000/21
(100/x)*x=(6000000/21)*x       - we multiply both sides of the equation by x
100=285714.28571429*x       - we divide both sides of the equation by (285714.28571429) to get x
100/285714.28571429=x
0.00035=x
x=0.00035

now we have:
21 is 0.00035% of 6000000
