Answer 2

Let's simplify each expression step by step:

1. 16/81 × 4/17 × 81/16

   First, notice that the numerator and denominator in each fraction have common factors. Cancel out common factors:

   (16/16) × (4/4) × (81/81) = 1 × 1 × 1 = 1

2. 72/49 × 5/19 × 49/36

   Again, notice the common factors:

   (72/36) × (5/5) × (49/49) = 2 × 1 × 1 = 2

3. 116/82 × 41/17 × 51/232

   Simplify by canceling common factors:

   (116/232) × (41/41) × (51/17) = 0.5 × 1 × 3 = 1.5

So, each of the expressions simplifies to:

1. 16/81 × 4/17 × 81/16 = 1
2. 72/49 × 5/19 × 49/36 = 2
3. 116/82 × 41/17 × 51/232 = 1.5
