Let's solve this step by step.
The worksheet is about
converting fraction models (visual representations) into decimals, specifically focusing on
tenths and
hundredths.
---
🔍 Understanding the Models:
-
Problems 1–4: Each rectangle is divided into
10 equal vertical strips → represents
tenths.
- So, each shaded strip =
0.1
- Total shaded parts / 10 = decimal
-
Problems 5–8: Each square is divided into
100 small squares → represents
hundredths.
- So, each small shaded square =
0.01
- Total shaded squares / 100 = decimal

✔ Step-by-step Solutions:
####
1.
- 3 out of 10 strips are shaded.
- $ \frac{3}{10} = 0.3 $
-
✔ Answer: 0.3
####
2.
- 7 out of 10 strips are shaded.
- $ \frac{7}{10} = 0.7 $
-
✔ Answer: 0.7
####
3.
- 6 out of 10 strips are shaded.
- $ \frac{6}{10} = 0.6 $
-
✔ Answer: 0.6
####
4.
- All 10 strips are shaded.
- $ \frac{10}{10} = 1.0 $
-
✔ Answer: 1.0
---
####
5.
- The grid has 100 squares.
- Count shaded squares:
- Left side: 5 full columns (each 10 squares) → 5 × 10 = 50
- Plus 5 more in the next column → total = 55
- $ \frac{55}{100} = 0.55 $
-
✔ Answer: 0.55
####
6.
- Full columns: 6 columns → 6 × 10 = 60
- Plus 5 more in the 7th column → total = 65
- $ \frac{65}{100} = 0.65 $
-
✔ Answer: 0.65
####
7.
- Full columns: 4 columns → 4 × 10 = 40
- No extra squares → total = 40
- $ \frac{40}{100} = 0.40 $ or just
0.4
-
✔ Answer: 0.40 (or
0.4)
####
8.
- Full columns: 7 columns → 7 × 10 = 70
- Plus 9 more in the 8th column → total = 79
- $ \frac{79}{100} = 0.79 $
-
✔ Answer: 0.79

📝 Final Answers:
| Problem | Decimal |
|--------|--------|
| 1 | 0.3 |
| 2 | 0.7 |
| 3 | 0.6 |
| 4 | 1.0 |
| 5 | 0.55 |
| 6 | 0.65 |
| 7 | 0.40 |
| 8 | 0.79 |

✔ Summary:
- For
tenths (10 parts): count shaded parts ÷ 10 → decimal
- For
hundredths (100 parts): count shaded squares ÷ 100 → decimal
This helps students visualize how fractions relate to decimals!
