What is 2.5 percent of 1234 - 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 1234 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 1234 is 100%, so we can write it down as 1234=100%.
4. We know, that x is 2.5% of the output value, so we can write it down as x=2.5%.
5. Now we have two simple equations:
1) 1234=100%
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:
1234/x=100%/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 what is 2.5% of 1234

1234/x=100/2.5
(1234/x)*x=(100/2.5)*x       - we multiply both sides of the equation by x
1234=40*x       - we divide both sides of the equation by (40) to get x
1234/40=x
30.85=x
x=30.85

now we have:
2.5% of 1234=30.85
