29 is what percent of 1389 - 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 1389 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 1389, so we can write it down as 100%=1389.
4. We know, that x% equals 29 of the output value, so we can write it down as x%=29.
5. Now we have two simple equations:
1) 100%=1389
2) x%=29
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%=1389/29
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 29 is what percent of 1389

100%/x%=1389/29
(100/x)*x=(1389/29)*x       - we multiply both sides of the equation by x
100=47.896551724138*x       - we divide both sides of the equation by (47.896551724138) to get x
100/47.896551724138=x
2.0878329733621=x
x=2.0878329733621

now we have:
29 is 2.0878329733621% of 1389
