Let's go through each statement and determine if it is true or false:<br /><br />a) $270\in N$ - True. 270 is a natural number.<br />A) $1\frac {2}{3}\in N$ - False. 1 2/3 is not a natural number.<br />H) $18\in Z$ - True. 18 is an integer.<br />H) $22\frac {7}{8}\notin N$ - True. 22 7/8 is not a natural number.<br />6) $1\in N$ - True. 1 is a natural number.<br />e) $14\notin N$ - False. 14 is a natural number.<br />K) $0\in Z$ - True. 0 is an integer.<br />0) $-14,2\notin Z$ - False. -14.2 is not an integer.<br />B) $0\in N$ - False. 0 is not a natural number.<br />ik) $-7\in N$ - False. -7 is not a natural number.<br />, JI) $-27\in Z$ - True. -27 is an integer.<br />i<br />r) $-70\in N$ - False. -70 is not a natural number.<br />3) $-\frac {1}{4}\in N$ - False. -1/4 is not a natural number.<br />, M) $22\frac {7}{8}\notin Z$ - True. 22 7/8 is not an integer.<br />II) $-14,2\in Z$ - False. -14.2 is not an integer.<br /><br />So, the correct answers are:<br />a) True<br />A) False<br />H) True<br />H) True<br />6) True<br />e) False<br />K) True<br />0) False<br />B) False<br />ik) False<br />, JI) True<br />i<br />r) False<br />3) False<br />, M) True<br />II) False
