Answer: 5
Step-by-step explanation:[tex]1\frac{1}{4} = \frac{5}{4}[/tex], [tex]1\frac{1}{2} = \frac{3}{2}[/tex], and [tex]2\frac{1}{4} = \frac{9}{4}[/tex].
Do [tex]\frac{5}{4} * \frac{3}{2} * \frac{9}{4}[/tex] straight across. That equals 5. Probably... Sorry, im not very good at math... But i like to help!
