Answer 1

$(3 \frac{1}{9} \div 3 \frac{4}{9} + \frac{3}{31} ) \div \frac{1}{4} - 3 \frac{2}{7} = ( \frac{28}{9} \times \frac{1}{ 3} \times \frac{4}{9} + \frac{3}{31} ) \times 4 - \frac{23}{7} = ( \frac{112}{243} + \frac{3}{31} ) \times 4 - \frac{23}{7} = \frac{4201}{7533} \times 4 - \frac{23}{7} = \frac{16804}{7533} - \frac{23}{7} = - \frac{55631}{52731}$

Answer 2

(28/9 x 1/3 x 4/9 + 3/31) x 4 - 23/7=
=(112/243 + 3/31) x 4 - 23/7=
=4201/7533 x 4 - 23/7=
=16804/7533 - 23/7=
=55631/52731
