43 is what percent of 1530 - 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 1530 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 100% equals 1530, so we can write it down as 100%=1530.
4. We know, that x% equals 43 of the output value, so we can write it down as x%=43.
5. Now we have two simple equations:
1) 100%=1530
2) x%=43
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:
100%/x%=1530/43
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 43 is what percent of 1530

100%/x%=1530/43
(100/x)*x=(1530/43)*x       - we multiply both sides of the equation by x
100=35.581395348837*x       - we divide both sides of the equation by (35.581395348837) to get x
100/35.581395348837=x
2.8104575163399=x
x=2.8104575163399

now we have:
43 is 2.8104575163399% of 1530
