347.78 is what percent of 3879 - 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 3879 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 3879, so we can write it down as 100%=3879.
4. We know, that x% equals 347.78 of the output value, so we can write it down as x%=347.78.
5. Now we have two simple equations:
1) 100%=3879
2) x%=347.78
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%=3879/347.78
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 347.78 is what percent of 3879

100%/x%=3879/347.78
(100/x)*x=(3879/347.78)*x       - we multiply both sides of the equation by x
100=11.153602852378*x       - we divide both sides of the equation by (11.153602852378) to get x
100/11.153602852378=x
8.9657128125806=x
x=8.9657128125806

now we have:
347.78 is 8.9657128125806% of 3879
