What is 33 percent of 1230 - 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 1230 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 1230 is 100%, so we can write it down as 1230=100%.
4. We know, that x is 33% of the output value, so we can write it down as x=33%.
5. Now we have two simple equations:
1) 1230=100%
2) x=33%
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:
1230/x=100%/33%
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 33% of 1230

1230/x=100/33
(1230/x)*x=(100/33)*x       - we multiply both sides of the equation by x
1230=3.030303030303*x       - we divide both sides of the equation by (3.030303030303) to get x
1230/3.030303030303=x
405.9=x
x=405.9

now we have:
33% of 1230=405.9
