2007/135= 14 và 13/15

17/12 = 1 và 5/12

126/27= 4 và 18/27

311/39 = 7 và 38/39

ủng hộ nhé !

bạn quên à, 4 và 18/27 = 4 và 2/3 

rút gọn k

2007/135 = 223/15

126/27 = 14/3

17/12 = 17/12

311/39 = 311/39

223/15

14/3

17/12

311/39

2007/135 = 14/13/15

126/27 = 4/2/3

17/12 = 1/5/12

311/39 = 7/38/39

\(\frac{-2007}{135}=-14^{13}_{15}\)

\(\frac{-126}{27}=-4^2_3\)

\(\)

=14/13/15

=4/2/3

=1/1/12

=7/38/39
