33. Divide Mixed Numbers An average male Giant Panda weighs 1 1/5 times as much as an average adult female. If the weight of an average male is 330 lbs, how much does the average female weigh? Who weighs more, the male or female?

34. Divide Mixed Numbers An average male Giant Panda weighs 1 1/5 times as much as an average adult female. If the weight of an average male is 330 lbs, how much does the average female weigh? Who weighs more, the male or female? Since it says the male weighs 1 1/5 times as much, the male weighs more.

35. Divide Mixed Numbers An average male Giant Panda weighs 1 1/5 times as much as an average adult female. If the weight of an average male is 330 lbs, how much does the average female weigh? It says the average male weighs 330 lbs, will the answer be more or less than that?

36. Divide Mixed Numbers An average male Giant Panda weighs 1 1/5 times as much as an average adult female. If the weight of an average male is 330 lbs, how much does the average female weigh? It says the average male weighs 330 lbs, will the answer be more or less than that? Since the average male weighs more, the female must weighs less than 330 lbs.

37. Divide Mixed Numbers An average male Giant Panda weighs 1 1/5 times as much as an average adult female. If the weight of an average male is 330 lbs, how much does the average female weigh? Since the answer will be less than 330 lbs, do we multiply or divide? In other words, starting with 330 lbs and knowing the answer will be less than that, which operation would give us an answer of less than 330 lbs?

38. Divide Mixed Numbers An average male Giant Panda weighs 1 1/5 times as much as an average adult female. If the weight of an average male is 330 lbs, how much does the average female weigh? Since the answer will be less than 330 lbs, do we multiply or divide? Dividing will make the answer less than 330 lbs. What is the exact answer?

39. Divide Mixed Numbers An average male Giant Panda weighs 1 1/5 times as much as an average adult female. If the weight of an average male is 330 lbs, how much does the average female weigh? 1 330 ÷1 5 = 6 330 ÷ 5 = 55 x 6 330 5 275 1 x 6 = 1 =275
