What is 200 percent of 38.5 - 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 38.5 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 38.5 is 100%, so we can write it down as 38.5=100%.
4. We know, that x is 200% of the output value, so we can write it down as x=200%.
5. Now we have two simple equations:
1) 38.5=100%
2) x=200%
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:
38.5/x=100%/200%
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 200% of 38.5

38.5/x=100/200
(38.5/x)*x=(100/200)*x       - we multiply both sides of the equation by x
38.5=0.5*x       - we divide both sides of the equation by (0.5) to get x
38.5/0.5=x
77=x
x=77

now we have:
200% of 38.5=77
