Answer 2

To solve the expression 8.45 + (-4 1/5) + (-1 3/4), we can follow these steps:

1. Convert the mixed numbers to improper fractions: -4 1/5 = -4 + 1/5 = -4/1 + 1/5 = -20/5 + 1/5 = -19/5 -1 3/4 = -1 + 3/4 = -1/1 + 3/4 = -4/4 + 3/4 = -1/4

2. Add the fractions together: -19/5 + (-1/4)

To add fractions, we need to find a common denominator. In this case, the common denominator is 20, which is the least common multiple of 5 and 4.

3. Adjust the fractions to have a common denominator: -19/5 * 4/4 + (-1/4) * 5/5 = -76/20 + (-5/20)

4. Add the adjusted fractions: -76/20 + (-5/20) = (-76 - 5)/20 = -81/20

Therefore, 8.45 + (-4 1/5) + (-1 3/4) equals -81/20 or -4.05.
