7+9=11=16/11

Answer 2

Step-by-step explanation:

$given \\ 3 \div 4 - 5 \div 7 + 9 \div 11 \\ solve \: the \: first \: two \: terms \\ so \: that \: \: \\ 21 - 20 \div 28 \\ = 1 \div 28 \\ solve \: the \: last \: term \\ i.e. \: \: 1 \div 28 + 9 \div 11 \\ = 11 + 252 \div 308 \\ = 263 \div 308$

Therefore the answer
