1. We assume, that the number 800 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 800 is 100%, so we can write it down as 800=100%. 4. We know, that x is 8% of the output value, so we can write it down as x=8%. 5. Now we have two simple equations: 1) 800=100% 2) x=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: 800/x=100%/8% 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 8% of 800
800/x=100/8 (800/x)*x=(100/8)*x - we multiply both sides of the equation by x 800=12.5*x - we divide both sides of the equation by (12.5) to get x 800/12.5=x 64=x x=64
now we have: 8% of 800 tons =64 Tons I hope this helped!!
