To convert the weight of the suitcase from ounces to pounds, you can use the given ratio:
1 pound = 16 ounces.
To find how many pounds 176 ounces is, you divide the number of ounces by the number of ounces in a pound:
\[ \text{Weight in pounds} = \frac{\text{Weight in ounces}}{16} = \frac{176 \text{ ounces}}{16 \text{ ounces/pound}} = 11 \text{ pounds}. \]
Thus, the suitcase weighs 11 pounds.
