   Answer: (1) 286

   సమాధానం: (1) 286

   By BODMAS, 2/3 of 5/6 = 5/9 and 1/2 × 3/7 ÷ 15/14 = 3/14 × 14/15 = 1/5. The bracket is 5/9 + 6 − 1/5 = (25 + 270 − 9)/45 = 286/45, and 45 × 286/45 = 286.

   BODMAS ప్రకారం, 5/6 లో 2/3 వంతు = 5/9 మరియు 1/2 × 3/7 ÷ 15/14 = 3/14 × 14/15 = 1/5. బ్రాకెట్‌లోని విలువ 5/9 + 6 − 1/5 = (25 + 270 − 9)/45 = 286/45, మరియు 45 × 286/45 = 286.
