Answer 2

To solve the expression, let's break it down step by step:

1. Start by adding the fractions: 1/3 + 1/8 To add these fractions, we need a common denominator. The least common multiple of 3 and 8 is 24. So, we rewrite the fractions with a common denominator: 8/24 + 3/24 = 11/24

2. Now let's simplify the expression inside the parentheses: -2.1 + 3.7 = 1.6

3. Next, subtract the value we obtained in step 2 from the result of step 1: 11/24 - 1.6 To subtract a fraction from a decimal, we need to convert the fraction into a decimal. 11/24 is approximately 0.4583333 (rounded to seven decimal places). Subtracting 0.4583333 from 1.6 gives us 1.1416667 (rounded to seven decimal places).

4. Finally, subtract 6 whole units and 11/12 from the result of step 3: 1.1416667 - 6 11/12 To subtract a mixed number from a decimal, we need to convert the mixed number into a decimal. 6 11/12 is equivalent to 6.9166667 (rounded to seven decimal places). Subtracting 6.9166667 from 1.1416667 gives us -5.775 (rounded to three decimal places).

Therefore, the final result is approximately -5.775.
