Ответ:

37 1/5 ÷ 18 = 186/5 × 1/18 = 186/90 = 31/15

5 ÷ 3 4/9 = 5 × 9/31 = 45/31

31/15 - 45/31 = 961/465 - 675/465 = 286/465

286/465 × 3 = 286/155

6 - 286/155 = 930/155 - 286/155 = 644/155

29/30 + 14/45 = 87/90 + 28/90 = 115/90 = 23/18

23/18 + 47/54 = 69/54 + 47/54 = 116/54 = 58/27

63/10 × 58/27 = 3654/270 = 203/15

203/15 - 13 = 203/15 - 195/15 = 8/15

644/155 ÷ 8/15 = 644/155 × 15/8 = 9660/120 = 80 1/2
