2.5 is what percent of 10.3 - 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 10.3 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 10.3, so we can write it down as 100%=10.3.
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%=10.3
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%=10.3/2.5
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 10.3

100%/x%=10.3/2.5
(100/x)*x=(10.3/2.5)*x       - we multiply both sides of the equation by x
100=4.12*x       - we divide both sides of the equation by (4.12) to get x
100/4.12=x
24.271844660194=x
x=24.271844660194

now we have:
2.5 is 24.271844660194% of 10.3
