Выполните деление дробей 3:1\9 6:1\11 4:3\8 5:5\7 9:3\7 10:5\8 2:1 1\3 12:2 1\7

Выполним деление целого числа на обыкновенную дробь и получим: 3 : 1\\9 = 3 * 9/1 = 3 * 9 = 27; 6 : 1\\11 = 6 * 11/1 = 6 * 11 = 66; 4 : 3\\8 = 4 * 8/3 = (4 * 8 )/3 = 32/3 = 10 целых 2/3; 5 : 5\\7 = 5 * 7/5 = ( 5 * 7)/5 = (1 * 7)/ 1 = 7/1 = 7; 9 : 3\\7 = 9 * 7/3 = (9 * 7)/3 = 63/3 = 21; 10 : 5\\8 = 10 * 8/5 = (10 * 8)/5 = (2 * 8)/1 = 16/1 = 16; 2 :1 целую 1\\3 = 2 : (1 * 3 + 1)/3 = 2 : 4/3 = 2 * 3/4 = (2 * 3)/4 = (1 * 3)/2 = 3/2 = 1 целая 1/2; 12 : 2 целых 1\\7 = 12 : (2 * 7 + 1)/7 = 12 : 15/7 = 12 * 7/15 = (12 * 7)/15 = (4 * 7)/5 = 28/5 = 5 целая 3/5.
