Answer:
Haley completed 11/12 and has yet to finish 1/12 of her homework.
Step-by-step explanation:
[tex]\frac{8}{12} + \frac{3}{12} = \frac{8 + 3}{12} = \frac{11}{12}[/tex]
Haley completed 11/12 of her homework. To find how much she has left is simple subtraction:
[tex]\frac{12}{12} - \frac{11}{12} = \frac{1}{12}[/tex]
So Haley has 1/12 of her homework left to complete.
