Let's solve each of the expressions step by step.

### (b) $$ (8.36 + 3.89) \div (-0.28) $$

1. **Calculate the sum**: 
   $$
   8.36 + 3.89 = 12.25
   $$
2. **Divide by $$-0.28$$**:
   $$
   12.25 \div (-0.28) = -43.75
   $$

### (d) $$ 0.36 - (-8.67) \div (-0.3) + 0.82 $$

1. **Calculate the division**:
   $$
   -8.67 \div (-0.3) = 28.9
   $$
2. **Substitute back into the expression**:
   $$
   0.36 - 28.9 + 0.82
   $$
3. **Perform the operations from left to right**:
   - First, $$ 0.36 - 28.9 = -28.54 $$
   - Then, $$ -28.54 + 0.82 = -27.72 $$

### (f) $$ 2.34 + 3.1 \times (-0.1) + 0.2 $$

1. **Calculate the multiplication**:
   $$
   3.1 \times (-0.1) = -0.31
   $$
2. **Substitute back into the expression**:
   $$
   2.34 - 0.31 + 0.2
   $$
3. **Perform the operations from left to right**:
   - First, $$ 2.34 - 0.31 = 2.03 $$
   - Then, $$ 2.03 + 0.2 = 2.23 $$

### Final Results
- (b) $$ (8.36 + 3.89) \div (-0.28) = -43.75 $$
- (d) $$ 0.36 - (-8.67) \div (-0.3) + 0.82 = -27.72 $$
- (f) $$ 2.34 + 3.1 \times (-0.1) + 0.2 = 2.23 $$
- (b) -43.75 - (d) -27.72 - (f) 2.23

(b) \( (8.36+3.89) \div(-0.28) \) (d) \( 0.36-(-8.67) \div(-0.3)+0.82 \) (f) \( 2.34+3.1 \times(-0.1)+0.2 \)
