What is 35.8 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 35.8% of the output value, so we can write it down as x=35.8%.
5. Now we have two simple equations:
1) 139=100%
2) x=35.8%
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%/35.8%
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 35.8% of 139

139/x=100/35.8
(139/x)*x=(100/35.8)*x       - we multiply both sides of the equation by x
139=2.7932960893855*x       - we divide both sides of the equation by (2.7932960893855) to get x
139/2.7932960893855=x
49.762=x
x=49.762

now we have:
35.8% of 139=49.762
