21 is what percent of 48470 - 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 48470 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 48470, so we can write it down as 100%=48470.
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%=48470
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%=48470/21
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 48470

100%/x%=48470/21
(100/x)*x=(48470/21)*x       - we multiply both sides of the equation by x
100=2308.0952380952*x       - we divide both sides of the equation by (2308.0952380952) to get x
100/2308.0952380952=x
0.043325768516608=x
x=0.043325768516608

now we have:
21 is 0.043325768516608% of 48470
