77 is what percent of 18790 - 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 18790 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 18790, so we can write it down as 100%=18790.
4. We know, that x% equals 77 of the output value, so we can write it down as x%=77.
5. Now we have two simple equations:
1) 100%=18790
2) x%=77
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%=18790/77
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 77 is what percent of 18790

100%/x%=18790/77
(100/x)*x=(18790/77)*x       - we multiply both sides of the equation by x
100=244.02597402597*x       - we divide both sides of the equation by (244.02597402597) to get x
100/244.02597402597=x
0.40979244278872=x
x=0.40979244278872

now we have:
77 is 0.40979244278872% of 18790
