Answer:
[tex]\large \boxed{\text{32 small animals/wk, 136/mo, and 1640/yr}}[/tex]
Explanation:
The pellets from a barn owl often contain the remains of 4 or 5 small animals. Let's assume an average of 4.5 animals per day.
1. Animals per week
[tex]\text{Per week} =\dfrac{\text{1 pellet}}{\text{1 da}} \times \dfrac{\text{4.5 animals}}{\text{1 pellet }} \times \dfrac{\text{7 da}}{\text{1 wk}} = \textbf{32 animals/wk}[/tex]
2. Animals per year
[tex]\text{Per year} = \dfrac{\text{32 animals}}{\text{1 year}} \times \dfrac{\text{52 wk}}{\text{1 yr}} =\textbf{1640 animals/yr}[/tex]
3. Animals per month
[tex]\text{Per year} = \dfrac{\text{1640 animals}}{\text{1 year}} \times \dfrac{\text{1 yr wk}}{\text{12 mo}} = \textbf{136 animals/mo}\\\\\text{A barn owl eats $\large \boxed{\textbf{36 small animals/wk, 136/mo, and 1640/yr}}$}[/tex]
