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
