Question

efetue as divisoes: a) (+5) : (-3/2)= b) (-4) : (-3/5)= c) (-3) : (-2/9)= d) (-5/2) : (+2)= e) (+4/3) : (-2)= f) (-3/5) : (+0,1)=

Answer 1

= -[-10] =
= +10 = 10 c){-5 + [7 — (3 + 1) — 10] + 2} = = {-5 + [7 T4+4) — 10] + 2} =
= {-5 + [7 — 4 — 10] + 2} =
= {-5 +47] + 2} =
={-5 — 7 + 2} =
= {-10} = -10 b) (13 — 4)— 8 =
6. Resolva as expressbes. a) 5 + (3 — 1) = c) 12 - (7 - 3) = d) (20 - 3) 7 + 5 e) 5 - 3 +(2 - 5)1= f 3 — [5 — (4 — 6)1= 3 [5 (-2)] =
[5 + 2] = _3 = -4 g) 2 + [8 - (7 - 5) + 3] = + 3] =
= 2 + h) -8 + [4 - (7 - 13)- 1] + 5 -844 ±6) 1] + 5. =
