What is 450 percent of 389 - 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 389 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 389 is 100%, so we can write it down as 389=100%.
4. We know, that x is 450% of the output value, so we can write it down as x=450%.
5. Now we have two simple equations:
1) 389=100%
2) x=450%
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:
389/x=100%/450%
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 450% of 389

389/x=100/450
(389/x)*x=(100/450)*x       - we multiply both sides of the equation by x
389=0.22222222222222*x       - we divide both sides of the equation by (0.22222222222222) to get x
389/0.22222222222222=x
1750.5=x
x=1750.5

now we have:
450% of 389=1750.5
