Q.1 Evaluate each of the following:
(a) (-30) ÷ 10
(b) 50 ÷ (-5)
(c) (-36) ÷ (-9)
(d) (-49) ÷ (49)
(e) 13 ÷ [(-2) + 1]
(f) 0 ÷ (-12)
(g) (-31) ÷ [(-30) + (-1)]
(h) [(-36) ÷ 12] ÷ 3
(i) [(-6) + 5] ÷ [(-2) + 1]


Answer :

(a) (-30) ÷ 10 = -3 [ (-) ÷(+) = (-) ]
(b) 50 ÷(-5) = -10 [(+)÷(-)= (-)]
(c) (-36) ÷ (-9) = 4 [(-) ÷(-) = (+)]
(d) (-49) ÷ (49) = -1
(e) 13 ÷ [(-2) + 1] = 13 ÷ (-1) = -13
(f) 0 ÷ (-12) = 0
(g) (-31) ÷ [(-30) + (-1)]= (-31) ÷ (-31) = 1
(h) [(-36) ÷ 12] ÷ 3= (-3) ÷ 3 = -1
(i) [(-6) + 5] ÷ [(-2) + 1]= (-1) ÷(-1)= 1
