`4-3.6div4+0.2xx0.5=?`

Options

A. 3.2
B. 0.2
C. 1.65
D. 0.15

Answer

To solve the expression \( 4 - 3.6 \div 4 + 0.2 \times 0.5 \), we will follow the order of operations (PEMDAS/BODMAS):

1. **Identify the operations**: We have subtraction, division, and multiplication in the expression.

2. **Perform division first**:
\[ 3.6 \div 4 = 0.9 \]
Now, substitute this back into the expression:
\[ 4 - 0.9 + 0.2 \times 0.5 \]

3. **Next, perform multiplication**:
\[ 0.2 \times 0.5 = 0.1 \]
Substitute this back into the expression:
\[ 4 - 0.9 + 0.1 \]

4. **Now, perform subtraction**:
\[ 4 - 0.9 = 3.1 \]
Substitute this back into the expression:
\[ 3.1 + 0.1 \]

5. **Finally, perform addition**:
\[ 3.1 + 0.1 = 3.2 \]

Thus, the final answer is:
\[ \boxed{3.2} \]
