Пошаговое объяснение:
1) 4 5/12 - 3 7/18 = 4 15/36 - 3 14/36 = 1 1/36
2) 1 1/36 : 9,25 = 1 1/36 : 9 1/4 = 37/36 * 4/37 = 1/9
3) 1/9 + 5/6 = 2/18 + 15/18 = 17/18
4) 0,4 + 1/8 = 0,4 + 0,125 = 0,525
5) 0,525 + 0,75 = 1,275
6) 1,275 * 2/3 = 0,425 * 2 = 0,85 = 17/20
7) 17/18 : 17/20 = 17/18 * 20/17 = 10/9 = 1 1/9
ответ: 1 1/9
=========================
1) 3 7/15 * 0,25 = 3 7/15 * 1/4 = 52/15 * 1/4 = 13/15
2) 13/15 + 5/6 = 26/30 + 25/30 = 51/30 = 17/10 = 1 7/10
3) 1 7/10 - 1 2/5 = 1 7/10 - 1 4/10 = 3/10
4) 3/20 + 0,75 = 0,15 + 0,75 = 0,9
5) 5,4 : 0,9 = 6
6) 3/10 : 6 = 3/10 * 1/6 = 1/20
ответ: 1/20
