A koala weighs 20 pounds. In her pouch she carries her joy that weighs 20 ounces. What is the combined weigth of the adult koala

sdas [7]

Answer: The answer is 21.25 pounds.

Step-by-step explanation: Given that the weight of Akoala is 20 pounds. Also, she is carrying her joey with her having weight 20 ounces. We need to find the combined weight of the adult Akoala and her joey in ounces.

For that, first we need to conver ounces to pounds.

We know

$1~\textup{pound}=16~\textup{ounces}\\\\\Rightarrow 1~\textup{ounce}=\dfrac{1}{16}~\textup{pounds}\\\\\Rightarrow 20~\textup{ounces}=\dfrac{1}{16}\times 20=\dfrac{5}{4}=1.25~\textup{pounds.}$

Therefore, the combined weight is given by

$W=20+1.25=21.25~\textup{pounds.}$

Thus, the answer is 21.25 pounds.
