Hello!
Let's set this up as a proportion.

First of all, we see that to get 1 to 8 we multiply by 8, so we could multiply 2.2 by 8 to find lbs.
2.2(8)=17.6
We could also cross multiply, giving us the equation below.
17.6= lbs
As we had a one, our answer is already in our equation.
Therefore, 8 kilograms is equal to 17.6 pounds.
I hope this helps!
