Answer 2

Let's break down the expression step by step:

1. Calculate the values within the parentheses:

   • $2 \times \frac{3}{8} = \frac{6}{8}$
   • $1 \times \frac{5}{6} = \frac{5}{6}$

2. Subtract the two values: $\frac{6}{8} - \frac{5}{6}$

To perform the subtraction, we need a common denominator. The least common multiple of 8 and 6 is 24. So, we'll convert both fractions to have a denominator of 24:

• $\frac{6}{8} = \frac{6 \times 3}{8 \times 3} = \frac{18}{24}$
• $\frac{5}{6} = \frac{5 \times 4}{6 \times 4} = \frac{20}{24}$

Now we can subtract: $\frac{18}{24} - \frac{20}{24} = \frac{-2}{24} = -\frac{1}{12}$

3. Divide the result by $\frac{1 \times 5}{8}$: $-\frac{1}{12} \div \frac{1 \times 5}{8} = -\frac{1}{12} \times \frac{8}{5} = -\frac{8}{60} = -\frac{2}{15}$

So, the final result of the expression is $-\frac{2}{15}$.
