Here's how I read your question: (3 1/2) divided by (1 1/4). One way to solve it: convert both mixed numbers to improper fractions: 3 1/2 = 7/2, and 1 1/4 = 5/4, so (7/2) / (5/4) = (7/2) * (4/5) = 28/10 = 2 8/10 = 2 4/5. Another way would be to convert to decimals and divide.

3 1/2 --> 3.5, 1 1/4 --> 1.25; 3.5 / 1.25 = 2.8 --> 2 8/10 = 2 4/5
