2) $\frac{3}{8}$ ÷ ($-\frac{5}{8}$)= $-\frac{3}{5}$

Answer 2

To simplify the expression (2 3/8 - 1 5/6) / (-5/8), let's convert the mixed numbers to improper fractions and perform the calculations step by step.

Step 1: Convert mixed numbers to improper fractions. 2 3/8 = (2 * 8 + 3) / 8 = 19/8 1 5/6 = (1 * 6 + 5) / 6 = 11/6

Step 2: Subtract the fractions. (19/8 - 11/6) / (-5/8)

To subtract fractions, we need a common denominator, which is 24 in this case.

(19/8 * 3/3 - 11/6 * 4/4) / (-5/8) (57/24 - 44/24) / (-5/8)

Step 3: Simplify the numerator. (57 - 44) / (-5/8) 13 / (-5/8)

Step 4: Divide by a fraction by multiplying with its reciprocal. 13 / (-5/8) * (8/-5) (13 * 8) / (-5 * 1) 104 / -5

Therefore, (2 3/8 - 1 5/6) / (-5/8) equals -20.8.
