What Is It Divisibility Rules for 4, 8, 11, and 12 Here are examples of numbers that are divisible by 4, 8, 11 and 12. Numbers Divisible by 4 8 11 12 28 32 33 48 812 96 242 180 124 176 495 240 2020 200 253 732
The Correct Answer and Explanation is:
Based on the image provided, the error is a minor typographical mistake within the table of examples.
Correct Answer
The error in the image is a typographical one. In the table, under the column for numbers divisible by 8, the number 32 is incorrectly presented as “32.”.
Explanation
The provided image from a math module aims to illustrate the divisibility rules for the numbers 4, 8, 11, and 12 by giving a list of examples. A detailed analysis of the mathematical content confirms that the examples chosen for each category are accurate. All the numbers listed in the table are correctly divisible by the number in their respective column header.
The only identifiable error is a small but clear typographical mistake. In the column labeled “8,” the first numerical entry is written as “32.”. The inclusion of a period after the number 32 is incorrect in this context. Integers in a simple list or table are not typically written with terminal punctuation. Since no other number in the grid has a similar mark, this appears to be an unintentional typo made during the creation of the document, rather than a conceptual or mathematical error.
To confirm the mathematical accuracy of the table:
- Divisibility by 4: All listed numbers (28, 812, 124, 2020) are correct, as the number formed by their last two digits is divisible by 4.
- Divisibility by 8: The numbers 32, 96, 176, and 200 are all correctly divisible by 8.
- Divisibility by 11: The numbers 33, 242, 495, and 253 are all divisible by 11, following the rule of alternating sums of digits.
- Divisibility by 12: The numbers 48, 180, 240, and 732 are all divisible by 12, as they are each divisible by both 3 and 4.
In conclusion, while the lesson’s mathematical examples are sound and serve their purpose, the document contains a minor formatting flaw with the stray period after the number 32.
