Answer:

(
(6)/(7) -
(1)/(3) ) is closer to
(1)/(2)

Explanation:


(2)/(15) +
(1)/(3) =
(2 + 5)/(15) =
(7)/(15)


(6)/(7) -
(1)/(3) =
(18-7)/(21) =
(11)/(21)


(7)/(15) ,
(1)/(2) ,
(11)/(21)

LCD (2, 15, 21) = 210


(98)/(210) ,
(105)/(210) ,
(110)/(210)

105 - 98 = 7

110 - 105 = 5 ⇒
(11)/(21) is closer to
(1)/(2) (
(6)/(7) -
(1)/(3) ) is closer to
(1)/(2)
