Alright, I need to tackle this set of problems step by step. Let's start by understanding each question individually.

**Problem 1:**
1. A bucket in a kitchen sink holds 20 liters.
   a) Calculate how many 250 ml cups of water the bucket will hold when it is filled to its maximum capacity.
   b) After all morning activities, there are still 6 liters left in the bucket.
      i) How much water is in $$ m $$?
      ii) How many 250 ml cups of water are still in the bucket?
      iii) What percentage is the 6 liters of the bucket's capacity?

**Problem 2:**
Three friends measure their heights in different units: Jotene is 155 cm, Petru is 1.65 m, and Thands is 1700 mm. Who is the tallest?

**Problem 3:**
Mpho has calculated that she needs 125 mm of ribbon for each gift she wraps. Calculate the total cost of the ribbon needed if the ribbon costs R8.90 per meter and she needs to wrap 50 gifts.

**Approach:**

1. **Problem 1:**
   - **Part a:** To find out how many 250 ml cups the bucket can hold when full, I'll divide the total capacity of the bucket by the volume of one cup.
     - Total capacity = 20 liters = 20,000 ml
     - Volume of one cup = 250 ml
     - Number of cups = 20,000 ml / 250 ml = 80 cups
   - **Part b(i):** After using some water, there are 6 liters left. To find out how much water was used, subtract the remaining from the total.
     - Water used = Total capacity - Remaining = 20 liters - 6 liters = 14 liters
   - **Part b(ii):** Now, I'll calculate how many 250 ml cups were used.
     - Number of cups used = 14 liters * 1000 ml/liter / 250 ml = 56 cups
   - **Part b(iii):** To find the percentage of the bucket that's still full, divide the remaining water by the total capacity and multiply by 100.
     - Percentage full = (6 liters / 20 liters) * 100 = 30%

2. **Problem 2:**
   - To determine who is the tallest, I'll convert all heights to the same unit, preferably meters.
     - Jotene: 155 cm = 1.55 m
     - Petru: 1.65 m
     - Thands: 1700 mm = 1.70 m
   - Comparing the heights:
     - Jotene: 1.55 m
     - Petru: 1.65 m
     - Thands: 1.70 m
   - Thands is the tallest at 1.70 m.

3. **Problem 3:**
   - Mpho needs 125 mm of ribbon per gift. First, convert this to meters since the cost is per meter.
     - 125 mm = 0.125 meters
   - Total ribbon needed = 0.125 meters/gift * 50 gifts = 6.25 meters
   - Cost per meter = R8.90
   - Total cost = 6.25 meters * R8.90/meter = R55.625

**Double-Checking:**
- For Problem 1, ensuring the units are consistent and calculations are accurate.
- For Problem 2, confirming the unit conversions and comparisons.
- For Problem 3, verifying the conversion from millimeters to meters and the multiplication for total cost.

Everything seems to add up correctly. No discrepancies found in the calculations.

1. a) The bucket can hold 80 cups of 250 ml each when filled to its maximum capacity. b) i) 14 liters of water were used. ii) There are 56 cups of water remaining in the bucket. iii) 30% of the bucket is still full. 2. Thands is the tallest at 1.70 meters. 3. The total cost of the ribbon needed is R55.63.
