Let's assume the number 8 is 100% - because it's the output value of the task. 2. Let's make x the value we are looking for. 3. 100% equals 8, so we can write it down as 100%=8. 4. x% equals 1280 of the output value, so we can write it down as x%=1280. 5. That leaves us with two simple equations: 1) 100%=8 2) x%=1280 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%=8/1280 6. Now all you have to do is solve the equation and you get the answer.
7. Equation and workfor 1280 is what percent of 8
100%/x%=8/1280 (100/x)x=(8/1280)x - we multiply both sides of the equation by x 100=0.00625*x - we divide both sides of the equation by (0.00625) to get x 100/0.00625=x 16000=x x=16000
