Question

For every 3 dogs he owns, Paul needs 8 pounds of dog food per day. How many pounds of dog food will he need for 9 dogs for 2 days?

Answer 1

*Paul will need 24 pounds of dog food for 9 dogs for 2 days.*

I multiplied 3 x 3 to get 9, and what you do to the top, you have to do to the bottom (and vice versa).

So 8 x 3 = 24.
