Show answer & explanation

Correct answer: C

Explanation

The correct answer is Option 3 i.e. 25/18

6 $8\over 15$ ÷ $7\over 9$ of (1 $1\over 10$ + 5 $1\over 5$ ) + $2\over 5$ ÷ 7 $1\over 5$

= 98/15 ÷ 7/9 of (11/10 + 26/5) + 2/5 ÷ 36/5

= 98/15 ÷ 49/10 + 2/5 ÷ 36/5

= 98/15 × 10/49 + 2/5 × 5/36

= 4/3 + 1/18

= 25/18
