What is 35 percent of 138.21 - 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 138.21 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 138.21 is 100%, so we can write it down as 138.21=100%.
4. We know, that x is 35% of the output value, so we can write it down as x=35%.
5. Now we have two simple equations:
1) 138.21=100%
2) x=35%
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:
138.21/x=100%/35%
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% of 138.21

138.21/x=100/35
(138.21/x)*x=(100/35)*x       - we multiply both sides of the equation by x
138.21=2.8571428571429*x       - we divide both sides of the equation by (2.8571428571429) to get x
138.21/2.8571428571429=x
48.3735=x
x=48.3735

now we have:
35% of 138.21=48.3735
