77690 is what percent of 4 - 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 4 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 4, so we can write it down as 100%=4.
4. We know, that x% equals 77690 of the output value, so we can write it down as x%=77690.
5. Now we have two simple equations:
1) 100%=4
2) x%=77690
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%=4/77690
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 77690 is what percent of 4

100%/x%=4/77690
(100/x)*x=(4/77690)*x       - we multiply both sides of the equation by x
100=5.1486677822114E-5*x       - we divide both sides of the equation by (5.1486677822114E-5) to get x
100/5.1486677822114E-5=x
1942250=x
x=1942250

now we have:
77690 is 1942250% of 4
