Answer 3

1. -1 + (-3 3/5): To solve this expression, we need to convert the mixed number (-3 3/5) into an improper fraction.

-3 3/5 = -3 + 3/5 = (-15/5) + 3/5 = -15/5 + 3/5 = -12/5

Now, we can simplify the expression:

-1 + (-12/5) = -1 - (12/5) = -1 - (12/5) = -1 - 2(2/5) = -1 - 2/5 = -1 2/5

Therefore, the result is -1 2/5.

2. 0.25 - 3/4: To subtract these values, we need to convert the decimal 0.25 into a fraction.

0.25 = 25/100 = 1/4

Now, we can solve the expression:

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

Therefore, the result is -1/2.

3. -1.68 + (-1.68): Adding the negative values, we get:

-1.68 + (-1.68) = -1.68 - 1.68 = -3.36

Therefore, the result is -3.36.

4. -3.8 + 1.8: Adding the values, we get:

-3.8 + 1.8 = -2

Therefore, the result is -2.

5. 5 - 32: Subtracting the values, we get:

5 - 32 = -27

Therefore, the result is -27.

To summarize:

1. -1 + (-3 3/5) = -1 2/5
2. 0.25 - 3/4 = -1/2
3. -1.68 + (-1.68) = -3.36
4. -3.8 + 1.8 = -2
5. 5 - 32 = -27
