Let's solve the problem step by step.
We are given 10 thermometers, each showing a temperature in degrees Fahrenheit (°F). The scale on each thermometer goes from 0 to 50°F, with markings every 10 degrees and smaller tick marks between them. Each small tick mark represents
1 degree, since there are 10 small ticks between each 10-degree mark.
We need to read the temperature for each thermometer by observing where the red mercury line ends.

Top Row:
1.
First Thermometer:
The red column reaches
23°F.
- It's between 20 and 30.
- Counting up from 20: 3 small ticks → 20 + 3 =
23°F
2.
Second Thermometer:
The red column reaches
27°F.
- Between 20 and 30.
- 7 small ticks above 20 → 20 + 7 =
27°F
3.
Third Thermometer:
The red column reaches
8°F.
- Between 0 and 10.
- 8 small ticks above 0 →
8°F
4.
Fourth Thermometer:
The red column reaches
29°F.
- Just below 30.
- 9 small ticks above 20 → 20 + 9 =
29°F
5.
Fifth Thermometer:
The red column reaches
21°F.
- Between 20 and 30.
- 1 small tick above 20 →
21°F
---
Bottom Row:
6.
Sixth Thermometer:
The red column reaches
19°F.
- Between 10 and 20.
- 9 small ticks above 10 → 10 + 9 =
19°F
7.
Seventh Thermometer:
The red column reaches
31°F.
- Between 30 and 40.
- 1 small tick above 30 →
31°F
8.
Eighth Thermometer:
The red column reaches
38°F.
- Between 30 and 40.
- 8 small ticks above 30 → 30 + 8 =
38°F
9.
Ninth Thermometer:
The red column reaches
14°F.
- Between 10 and 20.
- 4 small ticks above 10 → 10 + 4 =
14°F
10.
Tenth Thermometer:
The red column reaches
34°F.
- Between 30 and 40.
- 4 small ticks above 30 → 30 + 4 =
34°F

📝 Explanation:
Each thermometer has a scale marked from 0 to 50°F. The large lines are at 10-degree intervals (0, 10, 20, etc.), and each space between them is divided into 10 smaller units (each representing 1°F). By counting how many small ticks above or below the nearest 10-degree mark the red line reaches, we can determine the exact temperature.
For example:
- If the red line is at the 3rd tick above 20, it’s 20 + 3 = 23°F.
- If it's just below 30, at the 9th tick above 20, that’s 29°F.
This method applies to all thermometers.
✔ All temperatures have been accurately read based on the visual position of the red column.
