Answer:
[tex]1\frac{1}{3}[/tex]
Step-by-step explanation:
Since the second mixed number is negative and the fraction is larger than the fraction of the first mixed number, you need to borrow from the first fraction's whole number to make a larger fraction and subtract:
[tex]3\frac{1}{6}=2\frac{7}{6}[/tex]
Subtract: [tex]2\frac{7}{6}-1\frac{5}{6}=1\frac{2}{6}=1\frac{1}{3}[/tex]
