What is 400 percent of 8.75 - 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 8.75 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 8.75 is 100%, so we can write it down as 8.75=100%.
4. We know, that x is 400% of the output value, so we can write it down as x=400%.
5. Now we have two simple equations:
1) 8.75=100%
2) x=400%
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:
8.75/x=100%/400%
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 400% of 8.75

8.75/x=100/400
(8.75/x)*x=(100/400)*x       - we multiply both sides of the equation by x
8.75=0.25*x       - we divide both sides of the equation by (0.25) to get x
8.75/0.25=x
35=x
x=35

now we have:
400% of 8.75=35
