Problem: "Janet has 24 marbles. She gives 1/3 of them to Mark and 
1/4 of what's left to Susan. How many does Janet have left?"

GPT-4 Turbo Solution:
Step 1: Calculate marbles given to Mark: 24 × 1/3 = 8 marbles
Step 2: Marbles remaining: 24 - 8 = 16 marbles
Step 3: Calculate marbles given to Susan: 16 × 1/4 = 4 marbles
