What is 42990 percent of 3 - 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 3 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 3 is 100%, so we can write it down as 3=100%.
4. We know, that x is 42990% of the output value, so we can write it down as x=42990%.
5. Now we have two simple equations:
1) 3=100%
2) x=42990%
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:
3/x=100%/42990%
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 42990% of 3

3/x=100/42990
(3/x)*x=(100/42990)*x       - we multiply both sides of the equation by x
3=0.0023261223540358*x       - we divide both sides of the equation by (0.0023261223540358) to get x
3/0.0023261223540358=x
1289.7=x
x=1289.7

now we have:
42990% of 3=1289.7
