To solve the problem, we need to determine the decimal value that best represents the amount shaded in each grid. Let's analyze each grid step by step.
Grid 1:
- The grid is divided into 100 smaller squares (10 rows and 10 columns).
- The shaded area covers 45 of these squares.
- The fraction of the shaded area is \( \frac{45}{100} \).
- Converting this fraction to a decimal: \( \frac{45}{100} = 0.45 \).
Answer for Grid 1: B. 0.45
Grid 2:
- The grid is divided into 10 vertical strips.
- The shaded area covers 8 of these strips.
- The fraction of the shaded area is \( \frac{8}{10} \).
- Converting this fraction to a decimal: \( \frac{8}{10} = 0.8 \).
Answer for Grid 2: C. 0.8
Grid 3:
- The grid is divided into 10 horizontal strips.
- The shaded area covers 4 of these strips.
- The fraction of the shaded area is \( \frac{4}{10} \).
- Converting this fraction to a decimal: \( \frac{4}{10} = 0.4 \).
Answer for Grid 3: D. 0.4
Grid 4:
- The grid is divided into 100 smaller squares (10 rows and 10 columns).
- The shaded area covers 28 of these squares.
- The fraction of the shaded area is \( \frac{28}{100} \).
- Converting this fraction to a decimal: \( \frac{28}{100} = 0.28 \).
Answer for Grid 4: D. 0.28
Grid 5:
- The grid is divided into 10 vertical strips.
- The shaded area covers 6 of these strips.
- The fraction of the shaded area is \( \frac{6}{10} \).
- Converting this fraction to a decimal: \( \frac{6}{10} = 0.6 \).
Answer for Grid 5: B. 0.6
Grid 6:
- The grid is divided into 10 horizontal strips.
- The shaded area covers 2 of these strips.
- The fraction of the shaded area is \( \frac{2}{10} \).
- Converting this fraction to a decimal: \( \frac{2}{10} = 0.2 \).
Answer for Grid 6: A. 0.2
Grid 7:
- The grid is divided into 100 smaller squares (10 rows and 10 columns).
- The shaded area covers 64 of these squares.
- The fraction of the shaded area is \( \frac{64}{100} \).
- Converting this fraction to a decimal: \( \frac{64}{100} = 0.64 \).
Answer for Grid 7: B. 0.64
Grid 8:
- The grid is divided into 100 smaller squares (10 rows and 10 columns).
- The shaded area covers 55 of these squares.
- The fraction of the shaded area is \( \frac{55}{100} \).
- Converting this fraction to a decimal: \( \frac{55}{100} = 0.55 \).
Answer for Grid 8: B. 0.55
Grid 9:
- The grid is divided into 10 vertical strips.
- The shaded area covers 7 of these strips.
- The fraction of the shaded area is \( \frac{7}{10} \).
- Converting this fraction to a decimal: \( \frac{7}{10} = 0.7 \).
Answer for Grid 9: C. 0.7
Final Answers:
1. B. 0.45
2. C. 0.8
