Question

40 ounces is equal to how many pounds? (1pound = 16 ounces)

Answer 1

`2.5\text{ pounds}`

Step-by-step explanation

To find the answer, we have to apply proportions:

`\begin{gathered} 1\text{ pound = 16 ounces} \\ x\text{ pounds = 40 ounces} \end{gathered}`

Now, cross-multiply:

`\begin{gathered} x\cdot16=1\cdot40 \\ \Rightarrow x=(40)/(16) \\ x=2.5 \end{gathered}`

Therefore, 40 ounces is equal to 2.5 pounds.
