What is 3.31 percent of 428 - 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 428 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 428 is 100%, so we can write it down as 428=100%.
4. We know, that x is 3.31% of the output value, so we can write it down as x=3.31%.
5. Now we have two simple equations:
1) 428=100%
2) x=3.31%
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:
428/x=100%/3.31%
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 3.31% of 428

428/x=100/3.31
(428/x)*x=(100/3.31)*x       - we multiply both sides of the equation by x
428=30.211480362538*x       - we divide both sides of the equation by (30.211480362538) to get x
428/30.211480362538=x
14.1668=x
x=14.1668

now we have:
3.31% of 428=14.1668
