1) -3,27+(-4,84)+(-2,64) = -5,91 + (-4,84) = -10,75

2) 6,51+7,65=14,16

3) -10,75+14,16= 14,16 - 10,75 = 3,41

Answer 2

Let's solve these equations step by step:

1. -27 + 14 + (-80) + 21 + (-28)

First, add the positive numbers: 14 + 21 = 35

Now, add the negative numbers: -27 + (-80) + (-28) = -135

Now, add the results together: 35 - 135 = -100

So, the answer is -100.

2. -3.27 + (-4.84) + 6.51 + (-2.64) + 7.65

First, add the negative and positive numbers separately:

-3.27 + (-4.84) + (-2.64) = -10.75

Now, add the positive numbers: 6.51 + 7.65 = 14.16

Now, add the results together: -10.75 + 14.16 = 3.41

So, the answer is 3.41.
