• A. 0.16
• B. 1.0
• C. 0.01
• D. 0.1

Answer 1

Answer:

D. 0.1

The answer is 0.1.

Using BODMAS rule (Multiplication first, then addition)

1. Multiply the first pair:
   $0.1 \times 0.8 = 0.08$

2. Multiply the second pair:
   $0.1 \times 0.2 = 0.02$

3. Add the two results together:
   $0.08 + 0.02 = \mathbf{0.1}$
