What is 3400 percent of 12 - 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 12 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 12 is 100%, so we can write it down as 12=100%.
4. We know, that x is 3400% of the output value, so we can write it down as x=3400%.
5. Now we have two simple equations:
1) 12=100%
2) x=3400%
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:
12/x=100%/3400%
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for what is 3400% of 12

12/x=100/3400
(12/x)*x=(100/3400)*x       - we multiply both sides of the equation by x
12=0.029411764705882*x       - we divide both sides of the equation by (0.029411764705882) to get x
12/0.029411764705882=x
408=x
x=408

now we have:
3400% of 12=408
