1 is what percent of 20.7 - 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 20.7 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 20.7, so we can write it down as 100%=20.7.
4. We know, that x% equals 1 of the output value, so we can write it down as x%=1.
5. Now we have two simple equations:
1) 100%=20.7
2) x%=1
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%=20.7/1
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 1 is what percent of 20.7

100%/x%=20.7/1
(100/x)*x=(20.7/1)*x       - we multiply both sides of the equation by x
100=20.7*x       - we divide both sides of the equation by (20.7) to get x
100/20.7=x
4.8309178743961=x
x=4.8309178743961

now we have:
1 is 4.8309178743961% of 20.7
