Answer 2

Let's solve these step by step:

1. -1/3 + 1/2: To add fractions with different denominators, we need to find a common denominator. The least common multiple (LCM) of 3 and 2 is 6.

-1/3 + 1/2 = (-2/6) + (3/6) = (3 - 2)/6 = 1/6

2. -5/24 + 11/36: The LCM of 24 and 36 is 72.

-5/24 + 11/36 = (-15/72) + (22/72) = (22 - 15)/72 = 7/72

3. 1/16 - 3/4: Again, we need a common denominator, which is 16.

1/16 - 3/4 = 1/16 - (12/16) = (1 - 12)/16 = -11/16

4. -2/3 - (-1/2): To subtract fractions, we can change the subtraction to addition by changing the sign of the second fraction.

-2/3 - (-1/2) = -2/3 + 1/2

Now, we need to find a common denominator, which is 6.

-2/3 + 1/2 = (-4/6) + (3/6) = (-4 + 3)/6 = -1/6

5. -5/18 - (-1/24): Again, we convert the subtraction to addition by changing the sign of the second fraction.

-5/18 - (-1/24) = -5/18 + 1/24

Now, let's find a common denominator, which is 72.

-5/18 + 1/24 = (-20/72) + (3/72) = (-20 + 3)/72 = -17/72

So, the results are:

1. -1/3 + 1/2 = 1/6
2. -5/24 + 11/36 = 7/72
3. 1/16 - 3/4 = -11/16
4. -2/3 - (-1/2) = -1/6
5. -5/18 - (-1/24) = -17/72
