Hint
How much of a warren can each rabbit dig in one hour?
Answer
2 hours.
Reasoning
The small rabbit can dig a warren in nine hours, so digs 1 /9 in one hour.
The medium rabbit can dig a warren in 6 hours, so digs 1 /6 in one hour.
The large rabbit can dig a warren in four and a half hours, so digs 1 /4.5 in one hour.
1 Hour = 1 /9 + 1 /6 + 1 /4.5
To make the denominators all the same, we can multiply through by 18 /18 to give:
1 Hour = 2 /18 + 3 /18 + 4 /18
1 Hour = 9 /18
1 Hour = 1 /2
So in one hour, they have dug half a warren, the whole warren will therefore take 2 hours.
