2.2 is what percent of 128.65 - 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 128.65 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 128.65, so we can write it down as 100%=128.65.
4. We know, that x% equals 2.2 of the output value, so we can write it down as x%=2.2.
5. Now we have two simple equations:
1) 100%=128.65
2) x%=2.2
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%=128.65/2.2
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 2.2 is what percent of 128.65

100%/x%=128.65/2.2
(100/x)*x=(128.65/2.2)*x       - we multiply both sides of the equation by x
100=58.477272727273*x       - we divide both sides of the equation by (58.477272727273) to get x
100/58.477272727273=x
1.7100660707346=x
x=1.7100660707346

now we have:
2.2 is 1.7100660707346% of 128.65
