What is 390 percent of 880 - 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 880 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 880 is 100%, so we can write it down as 880=100%.
4. We know, that x is 390% of the output value, so we can write it down as x=390%.
5. Now we have two simple equations:
1) 880=100%
2) x=390%
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:
880/x=100%/390%
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 390% of 880

880/x=100/390
(880/x)*x=(100/390)*x       - we multiply both sides of the equation by x
880=0.25641025641026*x       - we divide both sides of the equation by (0.25641025641026) to get x
880/0.25641025641026=x
3432=x
x=3432

now we have:
390% of 880=3432
