Answer 1

Resposta:

Explicação passo a passo:

a) 5/2+3/4=10/4+3/4=13/4

b)3/2+7/3=9/6+14/6=23/6

c)6/8+3/2=6/8+12/8=20/8 ou 5/2

d)9/3+1/4=36/12+3/12=39/12 simplificando 33/4

e)12/6-2/3=12/6-4/6=8/6 ou 4/3

f)6/5-2/3-1/3=18/15-10/15-5/15=3/15 ou 1/5

g)7/3+3/4+2/4=28/12+9/12+6/12=43/12

h) 6/7-1/3+4/3=18/21-7/21+28/21=39/21 ou 13/7

i) 4/2-1/6=12/6-1/6=11/6

j) 7/4-8/9=63/36-32/36=31/36

k) 10/5-3/6=60/30-15/30=45/30 ou3/2

l) 2/3+3/4+2/6= 8/12+9/12+4/12=21/12 ou 7/4
