What is 29.7 percent of 139 - 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 139 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 139 is 100%, so we can write it down as 139=100%.
4. We know, that x is 29.7% of the output value, so we can write it down as x=29.7%.
5. Now we have two simple equations:
1) 139=100%
2) x=29.7%
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:
139/x=100%/29.7%
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 29.7% of 139

139/x=100/29.7
(139/x)*x=(100/29.7)*x       - we multiply both sides of the equation by x
139=3.3670033670034*x       - we divide both sides of the equation by (3.3670033670034) to get x
139/3.3670033670034=x
41.283=x
x=41.283

now we have:
29.7% of 139=41.283
