What is 30 percent of 1300000 - 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 1300000 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 1300000 is 100%, so we can write it down as 1300000=100%.
4. We know, that x is 30% of the output value, so we can write it down as x=30%.
5. Now we have two simple equations:
1) 1300000=100%
2) x=30%
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:
1300000/x=100%/30%
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 30% of 1300000

1300000/x=100/30
(1300000/x)*x=(100/30)*x       - we multiply both sides of the equation by x
1300000=3.3333333333333*x       - we divide both sides of the equation by (3.3333333333333) to get x
1300000/3.3333333333333=x
390000=x
x=390000

now we have:
30% of 1300000=390000
