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]

(a) We have,


(-30) ÷ 10


=


= - 3


(b) We have,


50 ÷ (-5)


=


= - 10


(c) We have,


(-36) ÷ (-9)


=


= 4


(d) We have,


(-49) ÷ 49


=


= - 1


(e) We have,


13 ÷ [(-2) + 1]


= 13 ÷[-2 + 1]


= 13 ÷ (-1)


=


= - 13


(f) We have,


0 ÷ (-12)


=


= 0


(g) We have,


(-31) ÷ [(-30) + (-1)]


= (-31) ÷ [-30 – 1]


= (-31) ÷ (-31)


=


= 1


(h) We have,


[(-36) ÷ 12] ÷ 3


= ÷ 3


= (-3) ÷ 3


=


= - 1


(i) We have,


[(-6) + 5)] ÷ [(-2) + 1]


= [-6 + 5] ÷ [-2 + 1]


= (-1) ÷ (-1)


=


= 1
