21 is what percent of 1014 - 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 1014 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 1014, so we can write it down as 100%=1014.
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%=1014
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%=1014/21
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 1014

100%/x%=1014/21
(100/x)*x=(1014/21)*x       - we multiply both sides of the equation by x
100=48.285714285714*x       - we divide both sides of the equation by (48.285714285714) to get x
100/48.285714285714=x
2.0710059171598=x
x=2.0710059171598

now we have:
21 is 2.0710059171598% of 1014
