20 is what percent of 433 - 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 433 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 433, so we can write it down as 100%=433.
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%=433
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%=433/20
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 433

100%/x%=433/20
(100/x)*x=(433/20)*x       - we multiply both sides of the equation by x
100=21.65*x       - we divide both sides of the equation by (21.65) to get x
100/21.65=x
4.6189376443418=x
x=4.6189376443418

now we have:
20 is 4.6189376443418% of 433
