(viii) -12 is ___________ than -8 and -10 is ___________ than opposite of 5.

(ix) If +15 represents gain of $15; then +45 represents ___________; and -75 represents ___________. (x) If 30 m below sea level is represented by -30; then -95 represents ___________; and +450 represents ___________. (xi) If fall in temperature by 15° C is denoted by +15, then -115 denotes ___________; and +47 denotes ___________. (xii) Absolute value of +24 is ___________ and absolute value of -35 is ___________. (xiii) |-11| = ___________, |+11| = ___________ and - |-11| = ___________. (xiv) If absolute value of a number = the number itself; then the number is ___________ or ___________ (xv) The opposite of +46 is ___________ and that of -88 is ___________ II. Find the integer, using the number line, which is: (i) 5 more than 3 (ii) 9 less than 4 (iii) 12 more than -4 (iv) 8 less than 3 (v) 7 less than 0 (vi) 4 less than -6 ﻿III. State whether the statements are true or false:﻿ ﻿(i) The smallest integer is 0. (ii) The opposite of -17 is 17 (iii) The opposite of zero is zero. (iv) Every negative integer is smaller than 0. (v) 0 is greater than every positive integer. (vi) Since, zero is neither negative nor positive; it is not an integer.
