Let's solve the problems from the two images you've uploaded.

### Problem 2: Rounding to One Decimal Place
You need to round the given numbers to one decimal place.

1. **(a) 3.22**  
   Rounded to one decimal place: **3.2**
   
2. **(b) 4.36**  
   Rounded to one decimal place: **4.4**
   
3. **(c) 0.82**  
   Rounded to one decimal place: **0.8**
   
4. **(d) 0.76**  
   Rounded to one decimal place: **0.8**
   
5. **(e) 0.65**  
   Rounded to one decimal place: **0.7**
   
6. **(f) 4.98**  
   Rounded to one decimal place: **5.0**
   
7. **(g) 6.02**  
   Rounded to one decimal place: **6.0**
   
8. **(h) 7.07**  
   Rounded to one decimal place: **7.1**
   
9. **(i) 1.19**  
   Rounded to one decimal place: **1.2**

### Problem 3: Rounding to Significant Figures
For each number, we'll round it to 3 significant figures (s.f.), 2 significant figures, and 1 significant figure.

1. **Number: 613 752**
   - 3 s.f.: **614000** 
   - 2 s.f.: **610000** 
   - 1 s.f.: **600000** 

2. **Number: 1.6831**
   - 3 s.f.: **1.68** 
   - 2 s.f.: **1.7** 
   - 1 s.f.: **2** 

3. **Number: 8769.2**
   - 3 s.f.: **8770** 
   - 2 s.f.: **8800** 
   - 1 s.f.: **9000**
