6)-58 23/60
7)-13/25
8)13 3/20

Answer 2

Ответ:

1) 36,8+(-75,7)= -36,8-75,7= -112,5

2)-274,93+546,3= +(546,3-274,93)=271,37

3)862,9+(862,9)= 1725,8

4)-941,3+(-1245,97)=-941,3-1245,97=-2187,27

5)34/49+(-57/98)= 125/98

6)-16 7/15+(-41 11/12)= -58 23/60

7)-4+3 36/75= -13/25

8) 72 2/5+(-59 1/4)= 263/20 = 13,15

Answer 3

1. -36.8 + (-75.7) = -112.5
2. -274.93 + 546.3 = 271.37
3. 862.9 + 862.9 = 1725.8
4. -941.3 + (-1245.97) = -2187.27
5. 34/49 + (-57/98) = -2099/6862 (simplified fraction)
6. -16 7/15 + (-41 11/12) = -58 19/60 (simplified mixed number)
7. -4 + 3 36/75 = -4 12/25 (simplified mixed number)
8. 72 2/5 + (-59 1/4) = 12 27/20 (simplified mixed number)
