3/6 + 4/7 - 1/6= (3/4 x 2/3 ): 1/6=

3/6 + 4/7 - 1/6=
= 21/42 + 24/42 - 7/42
= 45/42 - 7/42
= 38/42 = 19/21

(3/4 x 2/3 ): 1/6=
= 6/12 × 6/1
= 36/12 = 3/1 = 3

3/6 + 4/7 -1 /6
= 21/42 + 24/42 - 7/42
= 45/42 - 7/42
= 38/42 = 19/21

( 3/4 x 2/3 ) : 1/6
= 1/2 : 1/6
= 1/2 x 6
= 3

Maaf ya kalau salah. Semoga membantu. Jadikan jawaban tercerdas ya.
