Simplify:
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.
