Erika: let's start with this - can you tell us how many acres the youngest daughter received (two fifths of seven-and-a-quarter equals what)? Then after that, how many acres were left for the other two daughters? Post back with answers to those 2 questions and we can go from there.

Divide 7.25 by 5 and multiply by 2. This will give first answer.

Subtract answer from original amount. Divide this answer by 5 and multiply by 3. This will give 2nd answer.

Subtract this answer from first answer and you have 3rd answer.

Glad to do your home work for u.
