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 7000 is 100%, so we can write it down as 7000=100%.
4. We know, that x is 7% of the output value, so we can write it down as x=7%.
5. Now we have two simple equations:
1) 7000=100%
2) x=7%
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:
7000/x=100%/7%
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 7% of 7000
7000/x=100/7
(7000/x)*x=(100/7)*x - we multiply both sides of the equation by x
7000=14.2857142857*x - we divide both sides of the equation by (14.2857142857) to get x
7000/14.2857142857=x
490=x
x=490
now we have:
7% of 7000=490
