2 is what percent of 649.171 - 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 649.171 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 649.171, so we can write it down as 100%=649.171.
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%=649.171
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%=649.171/2
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 649.171

100%/x%=649.171/2
(100/x)*x=(649.171/2)*x       - we multiply both sides of the equation by x
100=324.5855*x       - we divide both sides of the equation by (324.5855) to get x
100/324.5855=x
0.30808523486108=x
x=0.30808523486108

now we have:
2 is 0.30808523486108% of 649.171
