Answer 1

Ответ:

1) -100, 2) 3,41, 3) 89,144

Пошаговое объяснение:

1) -27+14+(-80)+21+(-28)= -100

2)  - 3,27+(-4,84)+6,51+(-2,64)+7,65 = 3,41

3)  11/48+13/72+(-17/48)+(-7/48) = 89/144

Answer 2

Let's solve each of these arithmetic expressions step by step:

1. -27 + 14 + (-80) + 21 + (-28): -27 + 14 equals -13. -80 + 21 equals -59. -13 + (-59) equals -72. -72 + (-28) equals -100. So, the answer is -100.

2. -3.27 + (-4.84) + 6.51 + (-2.64) + 7.65: -3.27 + (-4.84) equals -8.11. -8.11 + 6.51 equals -1.60. -1.60 + (-2.64) equals -4.24. -4.24 + 7.65 equals 3.41. So, the answer is 3.41.

3. 11/48 + 13/72 + (-17/48) + (-7/48): First, find a common denominator for all fractions, which is 144: (11/48) * (3/3) = 33/144 (13/72) * (2/2) = 26/144 (-17/48) * (3/3) = -51/144 (-7/48) * (3/3) = -21/144

   Now, add the fractions: 33/144 + 26/144 + (-51/144) + (-21/144) = (33 + 26 - 51 - 21) / 144 = (-13) / 144

So, the answer is -13/144.
