First I would convert the fraction to a mixed number, 7 9/13, 6 1/3, etc. 11/4 rewritten as a mixed number is 2 3/4 because 4 goes into 11 twice (if you need more help with mixed numbers get help from your teacher or look online)! Now we need to find out how many times 2 3/4 lbs. (1 soup can) goes into 20 pounds. I would convert the original fraction 11/4 into a decimal by dividing 11 by 4. Then it would be 20 lbs (carton) divided by 2.75 lbs. (can).
See if you can get the final answer using the equation:[tex]20/2.75 = x[/tex]
