ME AJUDEMMMMMMMMNNN​

Answer 1

a)    (9+5)/12 = 14/12 (:2) = 7/6

4,12  2                  12/4= 3x3=9       12/12=1x5=5

2,6   2

1,3    3

1,1

b) (3+4)/4 = 7/4

c)(9+4)/6 =13/6

d)(5+5+3)/15 = 13/15

e)(15+10+6)/30 = 31/30

f)(9-4)/6 = 5/6

g)(4-2)/6 = 2/6= 1/3

h)(10-9)/12 = 1/12

i)(3-2-1)/6 = 0
