Question

Jahnay wants to estimate how many ducks there are in her local park.

One day she puts a non-harmful tag on 20 of the ducks in the park.
The next day she catches 27 ducks and notices that 3 of these have a tag on them.
Work out an estimate for the total number of ducks in her local park.

Answer 1

44 aproximately

Explanation:

She puts a tag on 20 of them, the next day she catches 27 and notices 3 of them have a tag so we substract 27-3=24 we add 24 to the initial number of ducks (20) and the result is 44

Answer 2

Explanation:

27÷3×20=180

or

3/27=20/n =180

so the numbers of ducks in her local park is 180
