The correct answer I got was 22 cups. 11/2 ÷ 1/4 is how you set it up. Then, you do KCF which stands for keep, change, flip. So, your new expression is 11/2 × 4/1. You cross reduce 4 & 2 which makes the new expression 11/1 × 2/1. 11 times 2 is 22/1 which still equals 22.
        
                    
             
        
        
        
I would tell them to try their hardest and to not give up hen it seems  hard. Also I would tell them that if they need help they can ask for help from their teacher, parents, or friends if they do not understand what they are learning.
Hope this helped
