To solve this, you can first convert the mixed numbers to improper fractions:
3/4 = 3/4
1 1/4 = (4*1+1)/4 = 5/4
7 1/2 = (2*7+1)/2 = 15/2
2 1/4 = (4*2+1)/4 = 9/4
Now, multiply these fractions together:
(3/4) (5/4) (15/2) * (9/4) / 2
= (3 5 15 9) / (4 4 2 2)
= 2025 / 64
Therefore, the answer is 2025 / 64 or approximately 31.64.
