What is 125000 percent of 4.2 - 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 4.2 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 4.2 is 100%, so we can write it down as 4.2=100%.
4. We know, that x is 125000% of the output value, so we can write it down as x=125000%.
5. Now we have two simple equations:
1) 4.2=100%
2) x=125000%
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:
4.2/x=100%/125000%
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 125000% of 4.2

4.2/x=100/125000
(4.2/x)*x=(100/125000)*x       - we multiply both sides of the equation by x
4.2=0.0008*x       - we divide both sides of the equation by (0.0008) to get x
4.2/0.0008=x
5250=x
x=5250

now we have:
125000% of 4.2=5250
