2.5 is what percent of 319.7 - 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 319.7 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 319.7, so we can write it down as 100%=319.7.
4. We know, that x% equals 2.5 of the output value, so we can write it down as x%=2.5.
5. Now we have two simple equations:
1) 100%=319.7
2) x%=2.5
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%=319.7/2.5
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 2.5 is what percent of 319.7

100%/x%=319.7/2.5
(100/x)*x=(319.7/2.5)*x       - we multiply both sides of the equation by x
100=127.88*x       - we divide both sides of the equation by (127.88) to get x
100/127.88=x
0.78198310916484=x
x=0.78198310916484

now we have:
2.5 is 0.78198310916484% of 319.7
