What is 1230 percent of 1300 - 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 1300 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 1300 is 100%, so we can write it down as 1300=100%.
4. We know, that x is 1230% of the output value, so we can write it down as x=1230%.
5. Now we have two simple equations:
1) 1300=100%
2) x=1230%
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:
1300/x=100%/1230%
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 1230% of 1300

1300/x=100/1230
(1300/x)*x=(100/1230)*x       - we multiply both sides of the equation by x
1300=0.08130081300813*x       - we divide both sides of the equation by (0.08130081300813) to get x
1300/0.08130081300813=x
15990=x
x=15990

now we have:
1230% of 1300=15990
