Josefina lives near a duck pond. She wants to know how many ducks use the pond. She places leg bands on 12 ducks one day. A week later, she examines 20 ducks and finds that 3 of them have leg bands. About how many ducks use the pond? 80 29 160 50
1 answer:
Answer:
80
Step-by-step explanation:
This is calculated as:
(Number of ducks with bands × Number of examined ducks)/ Number of ducks found with leg band
= Number of ducks with bands = 12 ducks
Number of examined ducks = 20 ducks
Number of ducks found with leg band = 3 ducks
Hence:
12 × 20/3
= 240/3
= 80 ducks
Therefore, 80 ducks used the ponds
