Answer :
Since the ratio between the ducks and geese is 175: 63
Since he counted 4725 geese
Let us use the ratio method to find the number of ducks
Ducks: Geese
175 63
D. 4725
By using the cross multiplication
[tex]\begin{gathered} D\times63=175\times4725 \\ 63D=826875 \end{gathered}[/tex]Divide both sides by 63
[tex]\begin{gathered} \frac{63D}{63}=\frac{826875}{63} \\ D=13125 \end{gathered}[/tex]There were 13125 ducks
He counted 13125 ducks
