2 is what percent of 215.45 - 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 215.45 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 215.45, so we can write it down as 100%=215.45.
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%=215.45
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%=215.45/2
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 215.45

100%/x%=215.45/2
(100/x)*x=(215.45/2)*x       - we multiply both sides of the equation by x
100=107.725*x       - we divide both sides of the equation by (107.725) to get x
100/107.725=x
0.92828962636343=x
x=0.92828962636343

now we have:
2 is 0.92828962636343% of 215.45
