1) 2 38/45 - 1/15 = 2 38/45 - 3/45 =
= 2 35/45 = 2 7/9
2) 2 7/9 : 13 8/9 = 25/9 : 125/9 =
= 25/9 • 9/125 = 0,2
3) 3 3/65 • 26/99 = 198/65 • 26/99 = 0,8
4) 0,2 + 0,8 = 1
5) 18 1/2 - 13 7/9 = 18 9/18 - 13 14/18 =
= 17 27/18 - 13 14/18 = 4 13/18
6) 4 13/18 • 1/85 = 85/18 • 1/85 = 1/18
7) (1 : 1/18) • 0,5 = 18 • 0,5 = 9
ответ: 9

1) 3,75 : 1 1/2 = 3,75 : 1,5 = 2,5
2) 1,5 : 3 3/4 = 1,5 : 3,75 = 0,4
3) 0,4 • 2 1/2 = 0,4 • 2,5 = 1
4) 1 1/7 - 23/49 = 8/7 - 23/49 =
= 56/49 - 23/49 = 33/49
5) 33/49 : 22/147 = 33/49 • 147/22 = 4,5
6) 2,5 + 1 + 4,5 = 8
7) 2 : 3 1/5 = 2 : 16/5 = 2 • 5/16 = 5/8
8) 3 1/4 : 13 = 13/4 : 13 = 1/4
9) 1/4 : 2/3 = 1/4 • 3/2 = 3/8
10) 2 5/18 - 17/36 = 41/18 - 17/36 =
= 82/36 - 17/36 = 65/36
11) 65/36 • 18/65 = 1/2
12) 5/8 + 3/8 - 1/2 = 1 - 1/2 = 1/2
13) 8 : 1/2 = 8 • 2/1 = 16
ответ: 16

1) 13/18 • 9/26 = 1/4
2) 4,625 - 1/4 = 4 5/8 - 1/4 =
= 4 5/8 - 2/8 = 4 3/8
3) 4 3/8 : 9/4 = 35/8 • 4/9 = 35/18
4) 2,5 : 1/25 = 2
5) 2 : 6,75 = 2 : 6 3/4 = 2 : 27/4 =
= 2 • 4/27 = 8/27
6) 35/18 + 8/27 = 105/54 + 16/54 = 121/54
7) 121/54 : 1 53/68 = 121/54 : 121/68 =
= 121/54 • 68/121 = 68/54 = 34/27
8) 1/2 - 0,375 = 0,5 - 0,375 = 0,125
9) 0,125 : 0,125 = 1
10) 5/6 - 7/12 = 19/12 - 7/12 = 3/12 = 1/4 = 0,25
11) 1,4796 : 13,7 = 0,108
12) 0,358 - 0,108 = 0,25
13) 0,25 : 0,25 = 1
14) 1 + 1 = 2
15) 34/27 : 2 = 17/27
