Soluções para a tarefa
Resposta:
Explicação passo-a-passo:
1/4+5/4 = 6/4 = 3/2
2/10+4/10 = 6/10 = 3/5
5/12+3/12 = 8/12 = 2/3
3/9+1/9+8/9 = 12/9 = 4/3
Resposta:a) 5/3 + 7/3 => 12/3 => 4
b) 4/5 - 1/5 + 2/5 => 3/5 + 2/5 => 5/5 => 1
c) 1/6 + 3/6 - 7/6 => 4/6 - 7/6 => 3/6 (÷3) => 1/2
d) 3/4 + 1/4 + 7/4 => 4/4 + 7/4 => 11/4
e) - 1/9 - 3/9 -:5/9 => - 4/9 - 5/9 => -:9/9 => 1
f) 4/3 - 1/3 - 2/3 => 3/3 - 2/3 => 1/3
g) 8/5 - 10/5 + 1/5 => - 2/5 + 1/5 => -1/5
h) 1/7 + 2/7 - 17/7 => 3/7 - 17/7 => - 14/7
i) - 3/5 + 2/5 + 8/5 => - 1/5 + 8/5 => 7/5
j) - 2/6 - 1/6 + 3/6 => - 3/6 + 3/6=> 0
K) - 2/3 - 1/4 - 2/6 => - 8/12 - 3/12 - 2/6 =>
- 11/12 - 2/6 => -11/12 - 4/12 => -15/12
m) - 2/5 + 1/10 - 7/10 => - 4/10 - 7/10 =>
- 11/10
n) 3/5 - 2/3 - 1/2 => 9/15 - 1/2 => 18/30 - 15/30 => 3/30 (÷3) => 1/10
o) 6/5 - 1/10 + 3/10 => 12/10 - 1/10 => 2/10 + 3/10 => 5/10 (÷5) => 1/2
p) 1/2 - 3/4 - 4/3 => 2/4 - 3/4 - 4/3 => - 1/4 - 4/3 => - 3/12 - 16/12 => - 19/12
q) 1/7 - 2/5 => 5/35 - 14/35 => - 9/35
r) 4/3 + 1/5 + 2/7 => 20/15 + 3/15 + 2/7 => 23/15 + 2/7 => 161/105 + 30/105 = 191/105
s) 1/2 + 2/3 + 1/4 => 3/6 + 4/6 + 1/4 => 7/6 + 1/4 -=> 14/12 + 3/12 => 17/12
t) 3/4 - 1/2 - 7/6 => 3/4 - 2/4 - 7/6 => 1/4 - 7/6 => 3/12 - 14/12 => - 11/12
u) 2/3 x 1/5 => 2/15
v) - 1/2 x ( -1/5 ) => 1/10
w) 1/3x( - 4/7 ) => - 4/21
y) 3/5 x ( - 1/4 ) => - 3/20
