Answer 1

$frac{14}{21} = frac{2}{3}; \ frac{6}{9} = frac{2}{3}; \ frac{88}{99} = frac{8}{9}. \ \ frac{8 times 11}{33 times 4} = frac{2 }{3}; \ frac{18 times 25}{75 times 12} = frac{3}{2} = 1 frac{1}{2}; \ frac{6 times 7 + 5 times 7}{49} = frac{6 + 5}{7} = frac{11}{7}. \ \ frac{504}{1260} = frac{2 times 252}{5 times 252} = frac{2}{5},$
НОД(504, 1260) = 252.

НОД(102, 510) = 10,
НОК(102, 510) = (102 × 510) / 10 = 5202.

НОД(600, 140) = 50,
НОК(600, 140) = (600 × 140) / 50 = 1680.
