Answer 2

Let's simplify the expression step by step:

1. First, calculate the values within the parentheses:

   • 2/3 × 2/3 = 4/9
   • 1/2 × 1/2 = 1/4
   • 2/3 × 2/3 = 4/9
   • 2/3 × 1/2 = 2/6 = 1/3
   • 1/2 × 1/2 = 1/4

2. Now, substitute these values back into the expression:

9 × (4/9) - 4 × (1/4) ÷ 18 × (4/9) × (1/3) - 12 × (1/3) × (1/4)

3. Simplify each part of the expression:

• 9 × (4/9) = 4
• 4 × (1/4) = 1
• 18 × (4/9) = 8
• 8 × (1/3) = 8/3
• 12 × (1/3) = 4
• 4 × (1/4) = 1

4. Now, substitute these simplified values back into the expression:

4 - 1 ÷ 8/3 - 4

5. Perform the division and subtraction:

4 - (1 ÷ 8/3) - 4

To divide by a fraction (8/3), you can multiply by its reciprocal (3/8):

4 - (1 × 3/8) - 4

Now, calculate the products:

4 - 3/8 - 4

6. Subtract the fractions:

(4 - 4) - 3/8

7. Finally, subtract 4 from 4, which is 0:

0 - 3/8

8. The final result is -3/8.
