Answer 3

To solve the given expression, let's simplify each term step by step:

(-1 1/3 + (-2 1/15)) + (-2.43 + (-2.77))

Step 1: Convert mixed numbers to improper fractions: (-4/3 + (-31/15)) + (-2.43 + (-2.77))

Step 2: Add the fractions within each parenthesis: (-4/3 - 31/15) + (-2.43 - 2.77)

Step 3: Find a common denominator for each set of fractions: The common denominator for 3 and 15 is 15, so we multiply the first fraction by 5/5: ((-4/3) * (5/5) - 31/15) + (-2.43 - 2.77)

Step 4: Perform the calculations within each parenthesis: ((-20/15) - 31/15) + (-2.43 - 2.77)

Step 5: Combine the fractions within each parenthesis: (-51/15) + (-2.43 - 2.77)

Step 6: Subtract the fractions and decimals separately: -51/15 - 5.2

Step 7: Convert the fraction to a decimal: -51/15 = -3.4

Step 8: Perform the final subtraction: -3.4 - 5.2 = -8.6

Therefore, (-1 1/3 + (-2 1/15)) + (-2.43 + (-2.77)) equals -8.6.
