Let's solve this step by step. The task is to measure the length of each insect using the ruler provided and write the measurement in
centimeters (cm) and
millimeters (mm).
We will go through each insect one by one, estimate its length based on the ruler, and convert between cm and mm where needed.
---
🔹 Key Conversion:
- 1 cm = 10 mm
So, if an insect measures
3.5 cm, that’s
3 cm + 5 mm or
35 mm.
We'll read the measurements from the ruler:
---
1. Green Fly (Top)
- The fly starts at 0 and ends at
3 cm.
- So:
✔ 3 cm
✔ 30 mm (since 3 × 10 = 30)
>
Answer:
> CM:
3
> MM:
30

2. Ant
- The ant starts at 0 and ends just before 4 cm. Let's see:
- It reaches
3.8 cm (between 3 and 4, closer to 4).
- So:
✔ 3.8 cm
✔ 38 mm (because 3.8 × 10 = 38)
>
Answer:
> CM:
3.8
> MM:
38

3. Bee
- The bee starts at 0 and ends at
2.5 cm.
- So:
✔ 2.5 cm
✔ 25 mm
>
Answer:
> CM:
2.5
> MM:
25
---
4. Butterfly
- The butterfly spans from 0 to
3.2 cm.
- So:
✔ 3.2 cm
✔ 32 mm
>
Answer:
> CM:
3.2
> MM:
32
---
5. Grasshopper
- Starts at 0 and ends at
4.7 cm.
- So:
✔ 4.7 cm
✔ 47 mm
>
Answer:
> CM:
4.7
> MM:
47
---
6. Spider
- The spider stretches from 0 to
6.5 cm.
- So:
✔ 6.5 cm
✔ 65 mm
>
Answer:
> CM:
6.5
> MM:
65
---
7. Bat (Cartoon Dragon-like)
- This bat starts at 0 and ends at
4.2 cm.
- So:
✔ 4.2 cm
✔ 42 mm
>
Answer:
> CM:
4.2
> MM:
42
---
8. Small Bat (Bottom)
- This bat is smaller and ends at
2.3 cm.
- So:
✔ 2.3 cm
✔ 23 mm
>
Answer:
> CM:
2.3
> MM:
23
---
✔ Final Answers Table:
| Insect | CM | MM |
|---------------|--------|------|
| Green Fly | 3 | 30 |
| Ant | 3.8 | 38 |
| Bee | 2.5 | 25 |
| Butterfly | 3.2 | 32 |
| Grasshopper | 4.7 | 47 |
| Spider | 6.5 | 65 |
| Cartoon Bat | 4.2 | 42 |
| Small Bat | 2.3 | 23 |

📌 Notes:
- All measurements are approximate based on visual estimation from the image.
- Make sure to align the start of the insect with the 0 mark on the ruler.
- Each small tick is
1 mm, and every 10 ticks make
1 cm.
