1) frac{36}{540}

36 = 2 * 2 * 3 * 3

540 = 2 * 2 * 3 * 3 * 3 * 5

НОД = 2 * 2 * 3 * 3  = 36

frac{36}{540} =frac{36}{36} : frac{540}{36}  = frac{1}{15}

2) frac{135}{240}

135 = 3 * 3 * 3 * 5

240 = 2 * 2* 2 * 2 * 3 * 5

НОД = 3 * 5 = 15

frac{135}{240} = frac{135}{15}  : frac{15}{240}  = frac{9}{16}
