Question

1) (-4,2)+3; 2) (-90):15; 3) (7/12)-(-5/12); 4) (35)+(-8); 5) (-5/9)*(3/5); 6) (-100)*(0).

Answer 1

(-4,2) +3=-1,2
(-90):15=-6
(7/12)-(-5/12)=12/12=1
35+(-8)=27
(-5/9)×(3/5)=(-1/3)
-100×0=0

Answer 2

Let's calculate the given expressions:

1. (-4,2) + 3: The expression (-4,2) represents a tuple, so adding 3 to a tuple doesn't make sense. If you meant to write (-4) + 2, then the result would be -2.

2. (-90) : 15: Dividing -90 by 15, we get -6. So the result is -6.

3. (7/12) - (-5/12): Subtracting a negative number is the same as adding the positive counterpart. So (-5/12) becomes (5/12) when we remove the negative sign. Thus, the expression becomes (7/12) + (5/12), which is equal to 12/12 or 1.

4. 35 + (-8): Adding 35 and -8, we get 27. So the result is 27.

5. (-5/9) * (3/5): Multiplying the fractions, we get (-5/9) * (3/5) = -15/45, which can be simplified to -1/3.

6. (-100) * (0): Any number multiplied by zero results in zero. So the result is 0.

To summarize:

1. (-4,2) + 3 = -2
2. (-90) : 15 = -6
3. (7/12) - (-5/12) = 1
4. 35 + (-8) = 27
5. (-5/9) * (3/5) = -1/3
6. (-100) * (0) = 0
