Пошаговое объяснение:
3 3/7 : 1 5/11 - 26/49 * 2 1/52 = 1 2/7,
1) 3 3/7 : 1 5/11 = 24/7 : 16/11 = 24/7 * 11/16 = 33/14 = 2 5/14,
2) 26/49 * 2 1/52 = 26/49 * 105/52 = 15/14 = 1 1/14,
3) 2 5/14 - 1 1/14 = 1 4/14 = 1 2/7
24/7*11/16=6/7*11/4=3/7*11/2=33/14
26/49*105/52=1/7*15/2=15/14
33/14-15/14=18/14=9/7=1 2/7
