Sure, let's calculate each of the given percentages:

1. **20% of 300**
   $$
   20\% \times 300 = 0.20 \times 300 = 60
   $$
   
2. **25% of 64**
   $$
   25\% \times 64 = 0.25 \times 64 = 16
   $$
   
3. **70% of $$220^\circ$$**
   $$
   70\% \times 220^\circ = 0.70 \times 220^\circ = 154^\circ
   $$
   
4. **130% of R50**
   $$
   130\% \times \text{R}50 = 1.30 \times \text{R}50 = \text{R}65
   $$
   
5. **5% of R3,500,000**
   $$
   5\% \times \text{R}3{,}500{,}000 = 0.05 \times \text{R}3{,}500{,}000 = \text{R}175{,}000
   $$
   
6. **30% of 7 km**
   $$
   30\% \times 7\, \text{km} = 0.30 \times 7\, \text{km} = 2.1\, \text{km}
   $$
   
7. **15% of R24**
   $$
   15\% \times \text{R}24 = 0.15 \times \text{R}24 = \text{R}3.60
   $$
   
8. **114% of R80**
   $$
   114\% \times \text{R}80 = 1.14 \times \text{R}80 = \text{R}91.20
   $$

### Summary of Results:
1. **60**
2. **16**
3. **154°**
4. **R65**
5. **R175,000**
6. **2.1 km**
7. **R3.60**
8. **R91.20**

Here are the results: 1. 60 2. 16 3. 154° 4. R65 5. R175,000 6. 2.1 km 7. R3.60 8. R91.20

(1) \( 20 \% \) of 300 。 (2) \( 25 \% \) of 64 (3) \( 70 \% \) of \( 220^{\circ} \) (4) \( 130 \% \) of R50 (5) \( 5 \% \) of R3 \( 500000^{\text {- }} \) (6) \( 30 \% \) of 7 km (7) \( 15 \% \) of R24 (8) \( 114 \% \) of R80
