3 In Drew’s class, one-fifth of the boys are absent and two-fifths of the girls are absent. Bert believes that you multiply, thus two twenty-fifths of the class is absent. Elmo believes that means that a total of three-fifths of the class is absent. Ernie believes three-tenths of the class is absent. Kermit can’t figure out how much of the class is absent, but he believes it is somewhere between one-fifth and two-fifths. Analyze each character’s answer to determine if they are correct or not. From this make a conclusion on which character knows the most math.
