Answer 2

Ответ:

1)-15+(-14)=-15-14=29

2)-1/2+(-3/4)=-1/2-3/4=-2/4-3/4=-5/4= -1 1/4

3)-3/8+(+5/6)=-3/8+5/6=-9/24+20/24= 11/24

4)5/6+(+17)+7/8=5/6+17/1+7/8= 20/24+408/24+21/24=453/24=18 21/24=18 7/8

5)15/15-(+15/15)=15/15-15/15=0

6)-3/8+(-1/2)=-3/8-1/2=-3/8-4/8=-7/8

7)-5/6+(+1/4)=-5/6+1/4=-10/12 +3/12 = - 7/12

8)-1/8+(+5/)=?

9)5/9+(-8/9)=5/9-8/9=-3/9

10)3/4+(-3/4)=3/4-3/4=0

В 5 и 10 не уверена а на 8 не понятно что написано

Answer 3

Let's go step by step to solve each expression:

1. -15 + (-14) = -29
2. -1/2 + (-3/4) = -2/4 + (-3/4) = -5/4
3. -3/8 + (+5/6) = -9/24 + (+20/24) = 11/24
4. 5/6 + (+17) + 7/8 = 5/6 + 17 + 7/8 = (40/24 + 17 + 21/24) = 40/24 + 17/1 + 21/24 = (40 + 408 + 21)/24 = 469/24
5. 15/15 - (+15/15) = 1 - 1 = 0
6. -3/8 + (-1/2) = -6/16 + (-8/16) = -14/16 = -7/8
7. -5/6 + (+1/4) = -10/12 + 3/12 = -7/12
8. -1/8 + (+5/9) = -9/72 + 40/72 = 31/72
9. 5/9 + (-8/9) = -3/9 = -1/3
10. 3/4 + (-3/4) = 0 ​ Therefore, the final results of the given expressions are:

-15 + (-14) = -29 -1/2 + (-3/4) = -5/4 -3/8 + (+5/6) = 11/24 5/6 + (+17) + 7/8 = 469/24 15/15 - (+15/15) = 0 -3/8 + (-1/2) = -7/8 -5/6 + (+1/4) = -7/12 -1/8 + (+5/9) = 31/72 5/9 + (-8/9) = -1/3 3/4 + (-3/4) = 0
