14.25 is what percent of 1978 - 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 1978 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 1978, so we can write it down as 100%=1978.
4. We know, that x% equals 14.25 of the output value, so we can write it down as x%=14.25.
5. Now we have two simple equations:
1) 100%=1978
2) x%=14.25
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%=1978/14.25
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 14.25 is what percent of 1978

100%/x%=1978/14.25
(100/x)*x=(1978/14.25)*x       - we multiply both sides of the equation by x
100=138.80701754386*x       - we divide both sides of the equation by (138.80701754386) to get x
100/138.80701754386=x
0.72042467138524=x
x=0.72042467138524

now we have:
14.25 is 0.72042467138524% of 1978
