Name: 6 Use the fraction model to answer the question. Keivan begins playing his sister s video game. His sister already lost life out of the available 5. Then he loses 2 more in the course of the game. Keivan says that they have 2 5 left? Is he correct? A No, 2 5 is not correct because 5 5-2 5 = 3 5 No, 2 5 is not correct because 5 5-2 5 + 3 5 = 6 5 Yes, 2 5 is correct because 5 5-5 - 2 5 = 2 5 D Yes, 2 5 is correct because 5 5 + 5 + 5 2 = 2 5 5
