Answer 2

$1) \frac{35 + 28}{35 - 28} = \frac{63}{7} = \frac{63 \div 7}{7 \div 7} = \frac{9}{1} = 9$

$2) \frac{75 - 33}{75 + 33} = \frac{42}{108} = \frac{42 \div 6}{108 \div 6} = \frac{7}{18}$

$3) \frac{24 + 3}{24 - 3} = \frac{27}{21} = \frac{27 \div 3}{21 \div 3} = \frac{9}{7} = 1 \frac{2}{7}$

$4) \frac{15 + 6}{15 - 6} = \frac{21}{9} = \frac{21 \div 3}{9 \div 3} = \frac{7}{3} = 2 \frac{1}{3}$

$5) \frac{12 - 3}{12 + 3} = \frac{9}{15} = \frac{9 \div 3}{15 \div 3} = \frac{3}{5}$

$6) \frac{26 + 2}{26 - 2} = \frac{28}{24} = \frac{28 \div 4}{24 \div 4} = \frac{7}{6} = 1 \frac{1}{6}$
