[31] Sample answer: No. Denise added the fractions by adding the numerators and adding the denominators. To add fractions, you have to find a common denominator first. [32] Sample answer:

10 a. No, she can not do it. If she gives her oldest daughter 1 3 of the land, there is only 2 left. If 3 each of her younger daughters got 1 4, that would be 3 4. Since 3 4 is greater than 2, there is not 3 enough land left. b. If she gave her oldest daughter 1 2 of what she wants to give away, that s 1 4 of her land. That leaves 1 4 for her other three daughters. If she gives her other three daughters all the same amount, they would each get 1 12 of her land.
