Answer:
Twenty ducklings were swimming at the pond
Step-by-step 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
