Answer 2

To solve the expression (4 7/15 - 2 3/5) × 15 × (1 11/17 + 2 15/34) × 34, we'll follow the order of operations (PEMDAS/BODMAS) and simplify it step by step.

Step 1: Simplify the expressions within the parentheses.

4 7/15 - 2 3/5 = (75/15 + 7/15) - (39/5 + 3/5) = 82/15 - 42/5 = (82 - 126)/15 = -44/15

1 11/17 + 2 15/34 = (17/17 + 11/17) + (68/34 + 15/34) = 28/17 + 83/34 = (56 + 83)/34 = 139/34

After simplifying the expression, we have:

(-44/15) × 15 × (139/34) × 34

Step 2: Cancel out common factors.

(-44/15) × (15/1) × (139/34) × (34/1) = (-44 × 139) / (15 × 34)

Step 3: Perform the multiplication and division.

(-44 × 139) / (15 × 34) = -6108 / 510 = -12

Therefore, the value of the expression (4 7/15 - 2 3/5) × 15 × (1 11/17 + 2 15/34) × 34 is -12.
