Question

By the end of migration, Barnaby had counted 4,725 geese. If the ratio of ducks to geeseremained the same (175 to 63), how many ducks did he count?

Answer 1

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

`\begin{gathered} D*63=175*4725 \\ 63D=826875 \end{gathered}`

Divide both sides by 63

`\begin{gathered} (63D)/(63)=(826875)/(63) \\ D=13125 \end{gathered}`

There were 13125 ducks

He counted 13125 ducks
