1.55 is what percent of 20.2 - 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 20.2 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 20.2, so we can write it down as 100%=20.2.
4. We know, that x% equals 1.55 of the output value, so we can write it down as x%=1.55.
5. Now we have two simple equations:
1) 100%=20.2
2) x%=1.55
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%=20.2/1.55
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 1.55 is what percent of 20.2

100%/x%=20.2/1.55
(100/x)*x=(20.2/1.55)*x       - we multiply both sides of the equation by x
100=13.032258064516*x       - we divide both sides of the equation by (13.032258064516) to get x
100/13.032258064516=x
7.6732673267327=x
x=7.6732673267327

now we have:
1.55 is 7.6732673267327% of 20.2
