910.5 is what percent of 1255 - 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 1255 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 1255, so we can write it down as 100%=1255.
4. We know, that x% equals 910.5 of the output value, so we can write it down as x%=910.5.
5. Now we have two simple equations:
1) 100%=1255
2) x%=910.5
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%=1255/910.5
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 910.5 is what percent of 1255

100%/x%=1255/910.5
(100/x)*x=(1255/910.5)*x       - we multiply both sides of the equation by x
100=1.3783635365184*x       - we divide both sides of the equation by (1.3783635365184) to get x
100/1.3783635365184=x
72.549800796813=x
x=72.549800796813

now we have:
910.5 is 72.549800796813% of 1255
