Answer 3

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

Step 1: Simplify the innermost parentheses first. -5 4/5 + 8/5 × 6 1/4 Convert mixed numbers to improper fractions: -5 4/5 + 8/5 × 6 1/4 = (-29/5) + (8/5 × 25/4) = (-29/5) + (200/20) = (-29/5) + (10/1) = (-29/5) + (50/5) = (50 - 29)/5 = 21/5

Step 2: Calculate the division within the parentheses: 21/5 ÷ 14/15 Invert the second fraction and multiply: = 21/5 × 15/14 Simplify: = (21 × 15)/(5 × 14) = 315/70 Reduce the fraction: = 45/10 Divide both numerator and denominator by 5: = 9/2

Step 3: Add 7/8 to the result: 7/8 + 9/2 Convert 7/8 to a fraction with the same denominator as 9/2: = 7/8 + 36/8 = (7 + 36)/8 = 43/8

Therefore, the simplified result is 43/8.
