Let me carefully examine the image to solve the problem.
The task asks: "Which decimal number is illustrated?" and shows four 10×10 grids (each representing 1 whole), with some squares shaded. For each grid, there are three multiple-choice options, and students need to select the correct decimal and write it in words.
I'll analyze each grid one by one:
Top-left grid (orange):
- It's a 10×10 grid = 100 squares total
- Count shaded squares: The first 7 full columns (7×10 = 70 squares) plus 6 squares in the 8th column → 76 squares shaded
- So this represents 76/100 = 0.76
- Options: 0.70, 0.76, 0.66 → correct is 0.76
Top-right grid (yellow):
- 10×10 grid = 100 squares
- Shaded: 9 full columns (9×10 = 90) plus 9 squares in the 10th column → 99 squares shaded
- So this is 99/100 = 0.99
- Options: 0.90, 0.79, 0.99 → correct is 0.99
Bottom-left grid (light green):
- 10×10 grid
- Shaded: 8 full columns (8×10 = 80 squares)
- So this is 80/100 = 0.80 = 0.8
- Options: 0.8, 0.08, 0.7 → correct is 0.8
Bottom-right grid (dark green):
- 10×10 grid
- Shaded: 5 full columns (5×10 = 50) plus 3 squares in the 6th column → 53 squares shaded
- So this is 53/100 = 0.53
- Options: 0.53, 0.03, 1.53 → correct is 0.53
Since the question asks "Which decimal number is illustrated?" and there are four separate grids, I need to identify all four correct answers.
However, looking at the format, it appears this is a worksheet where students select from the given options for each grid. The final answer should be the four correct decimals corresponding to each grid.
Let me double-check my counting:
Top-left: 7 full columns (70) + 6 more = 76 → 0.76 ✓
Top-right: 9 full columns (90) + 9 more = 99 → 0.99 ✓
Bottom-left: 8 full columns = 80 → 0.8 ✓
Bottom-right: 5 full columns (50) + 3 more = 53 → 0.53 ✓
Final Answer: 0.76, 0.99, 0.8, 0.53
