Question

How much is 8% of 800 tons?

Answer 1

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!!
