88 is what percent of 21000000 - 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 21000000 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 21000000, so we can write it down as 100%=21000000.
4. We know, that x% equals 88 of the output value, so we can write it down as x%=88.
5. Now we have two simple equations:
1) 100%=21000000
2) x%=88
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%=21000000/88
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 88 is what percent of 21000000

100%/x%=21000000/88
(100/x)*x=(21000000/88)*x       - we multiply both sides of the equation by x
100=238636.36363636*x       - we divide both sides of the equation by (238636.36363636) to get x
100/238636.36363636=x
0.00041904761904762=x
x=0.00041904761904762

now we have:
88 is 0.00041904761904762% of 21000000
