Answer 2

To solve the expression (-6 5/12 + 3.5) * (1 5/7), let's break it down step by step:

1. Convert the mixed fractions to improper fractions:

   • 5/12 is already in improper form.
   • 1 5/7 as an improper fraction is (7*1 + 5)/7 = 12/7.

2. Perform the operations within the parentheses:

   • (-6 5/12 + 3.5) = -6 + 5/12 + 3.5 = -6 + 5/12 + 42/12 = -6 + 47/12 = -6 + 3 11/12 = -2 11/12

3. Multiply the two results:

   • (-2 11/12) * (12/7)

   To multiply, convert -2 11/12 to an improper fraction: -2 * 12/12 + 11/12 = -24/12 + 11/12 = -13/12.

   Now the expression is: (-13/12) * (12/7).

   The 12s in the numerator and denominator cancel out, leaving us with: -13/7.

So, (-6 5/12 + 3.5) * (1 5/7) equals -13/7.
