1st Method:

1(4/7) ÷ 2/3 - 9/14

⇛(7*4)/7 ÷ 2/3 - 9/14

⇛28/7 ÷ 2/3 - 9/14

Take LCM of 3 and 14 is 42.

⇛28/7 ÷ (28-27)/42

⇛28/7 ÷ 1/42

⇛28/7 × 42/1

⇛(28 × 6)/1

⇛168/1

⇛168 Ans.

2nd Method:

1(4/7) ÷ 2/3 - 9/14

⇛(7*4)/7 ÷ 2/3 - 9/14

⇛28/7 ÷ 2/3 - 9/14

⇛4/1 ÷ 2/3 - 9/14

Take LCM of 3 and 14 is 42.

⇛4/1 ÷ (28-27)/42

⇛4/1 ÷ 1/42

⇛4/1 × 42/1

⇛(4 × 42)/(1×1)

⇛164/1

⇛164 Ans.
