Answer 2

To solve the expression 1 2/3 - (6 7/12 - 8 5/18) ÷ 3.05, let's break it down step by step:

Step 1: Convert mixed numbers to improper fractions 1 2/3 becomes (3 * 1 + 2) / 3 = 5/3 6 7/12 becomes (12 * 6 + 7) / 12 = 79/12 8 5/18 becomes (18 * 8 + 5) / 18 = 149/18

Step 2: Simplify the expression inside the parentheses (79/12 - 149/18)

To subtract fractions with different denominators, we need to find a common denominator. The least common multiple (LCM) of 12 and 18 is 36.

Rewriting the fractions with the common denominator of 36: (79/12) * (3/3) = 237/36 (149/18) * (2/2) = 298/36

Now we can subtract the fractions: (237/36 - 298/36) = -61/36

Step 3: Divide the result by 3.05 To divide fractions, we multiply by the reciprocal of the divisor. (-61/36) ÷ (3.05/1) = (-61/36) * (1/3.05) = -61/109.8

Therefore, the simplified result of the expression 1 2/3 - (6 7/12 - 8 5/18) ÷ 3.05 is approximately -0.555.
