Answer 1

$\frac{52}{91} = \frac{4 \times 13}{7 \times 13} = \frac{4}{7} \\ \frac{42}{49} = \frac{6 \times 7}{7 \times 7} = \frac{6}{7} \\ \frac{40}{72} = \frac{5 \times 8}{9 \times 8} = \frac{5}{9} \\ \frac{56}{64} = \frac{7 \times 8}{8 \times 8} = \frac{7}{8} \\ \frac{21}{91} = \frac{3 \times 7}{13 \times 7} = \frac{3}{13} \\ \frac{36}{81} = \frac{4 \times 9}{9 \times 9} = \frac{4}{9} \\ \frac{54}{63} = \frac{9 \times 6}{9 \times 7} = \frac{6}{7} \\ \frac{18}{38} = \frac{2 \times 9}{2 \times 19} = \frac{9}{19} \\ \frac{15}{51} = \frac{3 \times 5}{3 \times 17} = \frac{5}{17} \\ \frac{57}{76} = \frac{3 \times 19}{4 \times 19} = \frac{3}{4} \\ \frac{60}{96} = \frac{5 \times 12}{8 \times 12} = \frac{5}{8} \\ \frac{4}{6} = \frac{2 \times 2}{2 \times 3} = \frac{2}{3} \\ \frac{42}{78} = \frac{7 \times 6}{13 \times 6} = \frac{7}{13} \\ \frac{39}{91} = \frac{13 \times 3}{13 \times 7} = \frac{3}{7} \\ \frac{12}{52} = \frac{3 \times 4}{13 \times 4} = \frac{3}{13}$
