What is 128 percent of 5.2 - 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 5.2 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 5.2 is 100%, so we can write it down as 5.2=100%.
4. We know, that x is 128% of the output value, so we can write it down as x=128%.
5. Now we have two simple equations:
1) 5.2=100%
2) x=128%
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:
5.2/x=100%/128%
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 128% of 5.2

5.2/x=100/128
(5.2/x)*x=(100/128)*x       - we multiply both sides of the equation by x
5.2=0.78125*x       - we divide both sides of the equation by (0.78125) to get x
5.2/0.78125=x
6.656=x
x=6.656

now we have:
128% of 5.2=6.656
