7.8 is what percent of 7000 - 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 7000 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 100% equals 7000, so we can write it down as 100%=7000.
4. We know, that x% equals 7.8 of the output value, so we can write it down as x%=7.8.
5. Now we have two simple equations:
1) 100%=7000
2) x%=7.8
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:
100%/x%=7000/7.8
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 7.8 is what percent of 7000

100%/x%=7000/7.8
(100/x)*x=(7000/7.8)*x       - we multiply both sides of the equation by x
100=897.4358974359*x       - we divide both sides of the equation by (897.4358974359) to get x
100/897.4358974359=x
0.11142857142857=x
x=0.11142857142857

now we have:
7.8 is 0.11142857142857% of 7000
