k. 6/7×14/2×4/21

=3/1×2/1×4/21

=24/21

=8/7

l. 8/12×(7/9+11/13)

=8/12×(91/117+99/117)

=8/12×(190/117)

=8/12×190/117

=380/351

m. 4/7×21/3+4/7×24/3

=12/3+96/21

=84/21+96/21

=180/21

n. 8/6÷6/8

=8/6×8/6

=64/36

=16/9

o. 7/49÷63/35

=7/49×35/63

=5/63

p. 8/5÷(3/4+5/6)

=8/5÷(18/24+20/24)

=8/5÷(38/24)

=8/5×25/38

=40/38

=20/19

q. (2/3÷8/9)÷27/16

=(2/3×9/8)÷27/16

=3/4÷27/16

=3/4×16/27

=4/9

r. -12/84÷65/13×56/49

=-12/84×13/65×49/56

=1/-0.025
