Solution
For this case we can convert the pounds to ounces first like this:
[tex]1lb\cdot\frac{16\text{ounces}}{1lb}=16ounces[/tex]and we can find the serving with the following operation:
[tex]\frac{16\text{ounces}}{1.6\text{ ounces/serving}}=10\text{servings}[/tex]then the final answer would be 10 servings
