21.25 is what percent of 1047 - 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 1047 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 1047, so we can write it down as 100%=1047.
4. We know, that x% equals 21.25 of the output value, so we can write it down as x%=21.25.
5. Now we have two simple equations:
1) 100%=1047
2) x%=21.25
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%=1047/21.25
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 21.25 is what percent of 1047

100%/x%=1047/21.25
(100/x)*x=(1047/21.25)*x       - we multiply both sides of the equation by x
100=49.270588235294*x       - we divide both sides of the equation by (49.270588235294) to get x
100/49.270588235294=x
2.0296084049666=x
x=2.0296084049666

now we have:
21.25 is 2.0296084049666% of 1047
