Пошаговое объяснение:
в)
1) 15 : 3 3/4 = 15 : 3,75 = 4
2) -10 1/2 : 1 1/2 = -10,5 : 1,5 = -7
3) -7 * 3/14 = -3/2 = -1,5
4) 4 -(-1,5) = 4 + 1,5 = 5,5
5) 1 1/4 - 1 23/52 = 1 13/52 - 1 23/52 = -10/52 =-5/26
6) 5,5 : (-5/26) = 55/10 * (-26/5) = -143/5 = -28,6
ответ: -28,6
=======================
г)
1) -7/15 - 14/45 = -21/45 - 14/45 = -35/45 = -7/9
2) -7/9 - 2/9 = -9/9 = -1
3) -(-1) * 10 1/3 = 10 1/3
4) -1 3/4 + 2 2/3 = -1 9/12 + 2 8/12 = 11/12
5) 1 1/11 * 11/12 = 12/11 * 11/12 = 1
6) 10 1/3 - 1 = 9 1/3
7) -1/4 + 3/7 = -7/28 + 12/28 = 5/28
8) 5/28 : 3/28 = 5/28 * 28/3 = 5/3 = 1 2/3
9) 1 2/3 + 1 = 2 2/3
10) 9 1/3 : 2 2/3 = 28/3 : 8/3 = 28/3 * 3/8 = 7/2 = 3,5
ответ: 3,5
