Answer 2

Let's solve the arithmetic expressions step by step:

1. 1/2 + (-1/3): To add fractions, we need a common denominator. The common denominator for 2 and 3 is 6. 1/2 = (1/2)(3/3) = 3/6 (-1/3) = (-1/3)(2/2) = -2/6

Now, we can add the fractions: 3/6 + (-2/6) = 1/6

So, 1/2 + (-1/3) = 1/6.

2. -1/4 - 1/3: To subtract fractions, we also need a common denominator. The common denominator for 4 and 3 is 12. (-1/4) = (-1/4)(3/3) = -3/12 (-1/3) = (-1/3)(4/4) = -4/12

Now, we can subtract the fractions: (-3/12) - (-4/12) = -3/12 + 4/12 = 1/12

So, -1/4 - 1/3 = 1/12.

3. 0/43 + (-3.2): Any number added to 0 is the number itself. 0/43 = 0

So, 0 + (-3.2) = -3.2

Therefore, 0/43 + (-3.2) = -3.2.
