Answer 1

the answer is 20

Explanation:

Answer 2

Twenty ducklings were swimming at the pond

Explanation:

Let

x------> the number of ducklings

y------> the number of adult ducks

we know that

x+y=24 ------> equation A

\frac{x}{y}=\frac{5}{1}

so

x=5y

y=0.20x ------> equation B

Substitute equation B in equation A

x+0.20x=24

1.20x=24

x=20 ducklings
