Soluções para a tarefa
Resposta:
Explicação passo a passo:
.
. 2/3 + 1/3 = (2 + 1)/3 = 3/3 = 1
.
. 4/5 + 1/5 = (4 + 1)/5 = 5/5 = 1
.
. 2/8 + 3/8 = (2 + 3)/8 = 5/8
.
. 5/12 + 4/12 = (5 + 4)/12 = 9/12 = 3/4 (simplificando por 3)
.
. 7/9 + 1/9 = (7 + 1)/9 = 8/9
.
. 8/15 + 3/15 = (8 + 3)/15 = 11/15
.
. 2/4 + 4/4 = (2 + 4)/4 = 6/4 = 3/2 (simplificando por 2)
.
. 4/6 + 4/6 = (4 + 4)/6 = 8/6 = 4/3 (simplificando por 2)
.
. 8/10 + 7/10 = (8 + 7)/10 = 15/10 = 3/2 (simplificando por 5)
.
. 5/12 + 8/12 = (5 + 8)/12 = 13/12
.
. 5/3 + 2/3 = (5 + 2)/3 = 7/3
.
. 1/4 + 2/4 = (1 + 2)/4 = 3/4
.
. 3/5 + 6/5 = (3 + 6)/5 = 9/5
.
. 7/3 + 2/3 = (7 + 2)/3 = 9/3 = 3
.
. 7/3 + 1/3 = (7 + 1)/3 = 8/3
.
. 2/7 + 11/7 = (2 + 11)/7 = 13/7
.
. 3/5 + 2/5 = (3 + 2)/5 = 5/5 = 1
.
. 4/7 + 2/7 + (4 + 2)/7 = 6/7
.
. 5/16 + 1/8 = 5/16 + 2/16 = (5 + 2)/16 = 7/16
.
. 2 + 1/3 = 6/3 + 1/3 = (6 + 1)/3 = 7/3
.
. 5/2 + 3/4 = 10/4 + 3/4 = (10 + 3)/4 = 13/4
.
. 3/2 + 7/3 = 9/6 + 14/6 = (9 + 14)/6 = 23/6
.
. 6/2 + 3/8 = 24/8 + 3/8 = (24 + 3)/8 = 27/8
.
. 9/3 + 1/4 = 36/12 + 3/12 = (36 + 3)/12 = 39/12 = 13/4
.
. 3/4 + 2/6 = 9/12 + 4/12 = (9 + 4)/12 = 13/12
.
. 3 3/8 + 1 1/8 = 27/8 + 9/8 = (27 + 9)/8 = 36/8 = 9/2
.
. 5 3/4 + 7 = 23/4 + 7/1 = 23/4 + 28/4 = (23 + 28)4 = 51/4
.
. 2 2/2 + 1/4 = 6/2 + 1/4 = 12/4 + 1/4 = (12 + 1)/4 = 13/4
.
OBS: o restante você tente resolver. Ok: ?
