2 is what percent of 1.215 - 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 1.215 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 1.215, so we can write it down as 100%=1.215.
4. We know, that x% equals 2 of the output value, so we can write it down as x%=2.
5. Now we have two simple equations:
1) 100%=1.215
2) x%=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%=1.215/2
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 2 is what percent of 1.215

100%/x%=1.215/2
(100/x)*x=(1.215/2)*x       - we multiply both sides of the equation by x
100=0.6075*x       - we divide both sides of the equation by (0.6075) to get x
100/0.6075=x
164.60905349794=x
x=164.60905349794

now we have:
2 is 164.60905349794% of 1.215
