What is 357 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 357% of the output value, so we can write it down as x=357%.
5. Now we have two simple equations:
1) 12=100%
2) x=357%
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%/357%
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 357% of 12

12/x=100/357
(12/x)*x=(100/357)*x       - we multiply both sides of the equation by x
12=0.28011204481793*x       - we divide both sides of the equation by (0.28011204481793) to get x
12/0.28011204481793=x
42.84=x
x=42.84

now we have:
357% of 12=42.84
