20 is what percent of 769.23 - 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 769.23 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 769.23, so we can write it down as 100%=769.23.
4. We know, that x% equals 20 of the output value, so we can write it down as x%=20.
5. Now we have two simple equations:
1) 100%=769.23
2) x%=20
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%=769.23/20
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 20 is what percent of 769.23

100%/x%=769.23/20
(100/x)*x=(769.23/20)*x       - we multiply both sides of the equation by x
100=38.4615*x       - we divide both sides of the equation by (38.4615) to get x
100/38.4615=x
2.6000026=x
x=2.6000026

now we have:
20 is 2.6000026% of 769.23
