618.5 is what percent of 770000 - 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 770000 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 770000, so we can write it down as 100%=770000.
4. We know, that x% equals 618.5 of the output value, so we can write it down as x%=618.5.
5. Now we have two simple equations:
1) 100%=770000
2) x%=618.5
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%=770000/618.5
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 618.5 is what percent of 770000

100%/x%=770000/618.5
(100/x)*x=(770000/618.5)*x       - we multiply both sides of the equation by x
100=1244.9474535166*x       - we divide both sides of the equation by (1244.9474535166) to get x
100/1244.9474535166=x
0.080324675324675=x
x=0.080324675324675

now we have:
618.5 is 0.080324675324675% of 770000
