Accepted Answer

### 1) Place a dot 0.5 way between the lines.
# Explanation:
## Step1: Understand 0.5 way
0.5 way means the midpoint between two lines. If the two lines represent values (say, left line as $ a $, right as $ b $), the midpoint is $ a + 0.5\times(b - a)=\frac{a + b}{2} $. For two vertical lines (assuming no labeled values yet, but conceptually midpoint), place the dot exactly in the middle.
## Step2: Visual placement
Between the two parallel vertical lines, find the center (equal distance from both) and mark the dot.

### 2) Place a dot 0.5 way between the lines.
# Explanation:
## Step1: Midpoint concept
0.5 way is the midpoint. With two closely spaced vertical lines, the midpoint is halfway between them.
## Step2: Placement
Measure (visually) the distance between the two lines and place the dot at the center.

### 3) Place a dot 0.2 way between the lines.
# Explanation:
## Step1: Understand 0.2 way
If the left line is $ a $ and right is $ b $, the position is $ a+0.2\times(b - a)=0.8a + 0.2b $. So 20% of the distance from the left line towards the right.
## Step2: Visual estimation
Estimate the distance between the two lines, take 20% of that distance from the left line, and place the dot there.

### 4) Place a dot 0.2 way between the lines.
# Explanation:
## Step1: 0.2 way calculation
For two closely spaced lines, 0.2 way from the left means $ 0.2\times \text{(distance between lines)} $ from the left line.
## Step2: Placement
Visually determine the distance between the two lines, move 20% of that distance from the left line, and mark the dot.

### 5) Place a dot 0.3 way between the lines.
# Explanation:
## Step1: 0.3 way formula
Position: $ a + 0.3\times(b - a)=0.7a+0.3b $ (30% from left, 70% from right).
## Step2: Visual placement
Estimate the distance between the two lines, move 30% of that distance from the left line, and place the dot.

### 6) Place a dot 0.3 way between the lines.
# Explanation:
## Step1: 0.3 way concept
For two closely spaced lines, 0.3 way from the left is $ 0.3\times \text{(distance between lines)} $ from the left.
## Step2: Placement
Visually find the distance between the lines, move 30% of that distance from the left line, and mark the dot.

### 7) Place a dot 0.5 way between the lines (values 2 and 3).
# Explanation:
## Step1: Calculate midpoint
The two values are 2 (left) and 3 (right). Midpoint (0.5 way) is $ \frac{2 + 3}{2}=2.5 $.
## Step2: Placement
Between the lines labeled 2 and 3, place the dot at the position corresponding to 2.5.

### 8) Place a dot 0.2 way between the lines (values 2 and 3).
# Explanation:
## Step1: Calculate position
Position $ = 2+0.2\times(3 - 2)=2 + 0.2\times1 = 2.2 $.
## Step2: Placement
From the line labeled 2, move 0.2 of the distance to 3 (since 3 - 2 = 1 unit), so place the dot at 2.2.

### 9) Place a dot 0.2 way between the lines (values 0.2 and 0.3).
# Explanation:
## Step1: Calculate position
Position $ = 0.2+0.2\times(0.3 - 0.2)=0.2+0.2\times0.1 = 0.22 $.
## Step2: Placement
From the line labeled 0.2, move 0.2 of the distance to 0.3 (0.3 - 0.2 = 0.1 unit), so place the dot at 0.22.

### 10) Place a dot 0.3 way between the lines (values 22 and 23).
# Explanation:
## Step1: Calculate position
Position $ = 22+0.3\times(23 - 22)=22 + 0.3\times1 = 22.3 $.
## Step2: Placement
From the line labeled 22, move 0.3 of the distance to 23 (23 - 22 = 1 unit), so place the dot at 22.3.

### 11) Place a dot 0.3 way between the lines (values 0.02 and 0.03).
# Explanation:
## Step1: Calculate position
Position $ = 0.02+0.3\times(0.03 - 0.02)=0.02+0.3\times0.01 = 0.023 $.
## Step2: Placement
From the line labeled 0.02, move 0.3 of the distance to 0.03 (0.03 - 0.02 = 0.01 unit), so place the dot at 0.023.

### Answers (Readings for labeled ones):
7) $ 2.5 $
8) $ 2.2 $
9) $ 0.22 $
10) $ 22.3 $
11) $ 0.023 $

(For unlabeled line placement, the dot is placed at the calculated/estimated position as per the fraction of the distance between the lines.)
