What is 31 percent of 3628 - 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 3628 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 3628 is 100%, so we can write it down as 3628=100%.
4. We know, that x is 31% of the output value, so we can write it down as x=31%.
5. Now we have two simple equations:
1) 3628=100%
2) x=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:
3628/x=100%/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 31% of 3628

3628/x=100/31
(3628/x)*x=(100/31)*x       - we multiply both sides of the equation by x
3628=3.2258064516129*x       - we divide both sides of the equation by (3.2258064516129) to get x
3628/3.2258064516129=x
1124.68=x
x=1124.68

now we have:
31% of 3628=1124.68
