What is 98.6 percent of 2.5 - 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 2.5 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 2.5 is 100%, so we can write it down as 2.5=100%.
4. We know, that x is 98.6% of the output value, so we can write it down as x=98.6%.
5. Now we have two simple equations:
1) 2.5=100%
2) x=98.6%
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:
2.5/x=100%/98.6%
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for what is 98.6% of 2.5

2.5/x=100/98.6
(2.5/x)*x=(100/98.6)*x       - we multiply both sides of the equation by x
2.5=1.0141987829615*x       - we divide both sides of the equation by (1.0141987829615) to get x
2.5/1.0141987829615=x
2.465=x
x=2.465

now we have:
98.6% of 2.5=2.465
