Question

At a pond there were 24 ducks swimming. The ratio of ducklings to adult ducks is 5:1. How many ducklings were swimming at the pond?

Answer 1

Twenty ducklings were swimming at the pond

Answer 2

Answer:

$20\ ducklings$

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

$x+0.20x=24$

$1.20x=24$

$x=20\ ducklings$
