Answer:
24
Step-by-step explanation:
Let's convert the 1st fraction to a fraction with the LCD:
[tex]1\frac{1}{4} *\frac{6}{6} =1\frac{6}{24}[/tex]
Let's convert the 2nd fraction to a fraction with the LCD:
[tex]\frac{1}{6} *\frac{4}{4} =\frac{4}{24}[/tex]
And we can't convert the last fraction because the denominator is already 24.
