Do 1 through 14

Solution

PIL import Image import pytesseract

Load the image

image_path = "/mnt/data/1733194983309ebys23yn.jpg" img = Image.open(image_path)

Perform OCR to extract text

extracted_text = pytesseract.image_to_string(img)

extracted_textBased on the text extracted, I will solve all the problems (1 through 14). Here's the breakdown:

Part 1: Use number sense to find the products

  1. 46×3=13846 \times 3 = 138
    4.6×3=13.84.6 \times 3 = 13.8
    0.46×3=1.380.46 \times 3 = 1.38

  2. 17×15=25517 \times 15 = 255
    17×1.5=25.517 \times 1.5 = 25.5
    17×0.15=2.5517 \times 0.15 = 2.55


Part 2: Find each product

  1. 27.4×7=191.827.4 \times 7 = 191.8
  2. 336×0.4=134.4336 \times 0.4 = 134.4
  3. 88×1.8=158.488 \times 1.8 = 158.4
  4. 4.02×9=36.184.02 \times 9 = 36.18
  5. 1.7×12=20.41.7 \times 12 = 20.4
  6. 105×0.4=42105 \times 0.4 = 42
  7. 1.4×32=44.81.4 \times 32 = 44.8
  8. 0.89×21=18.690.89 \times 21 = 18.69
  9. 44×18=79244 \times 18 = 792
  10. 0.3×279=83.70.3 \times 279 = 83.7
  11. 95×5.7=541.595 \times 5.7 = 541.5
  12. 46×0.46=21.1646 \times 0.46 = 21.16

Let me know if you need further clarifications or want details on any specific problem.


Questions for Expansion:

  1. How can you estimate results before calculating exact products?
