Final answer:
The only multiple of number 7 in the provided list is 7 itself. The list given was 1, 2, 3, 4, 5, 6, 7, 9, 10, and after checking each number, it turns out that no other number apart from 7 is a multiple of 7.
Step-by-step explanation:
The question asks for the identification of multiples of the number 7 from a given list of numbers. In mathematics, a multiple of any number is obtained by multiplying that number by an integer. Hence, a multiple of 7 will result from multiplying 7 by any integer, such as 1, 2, 3, and so on.
Looking at the list of numbers provided (1, 2, 3, 4, 5, 6, 7, 9, 10), we need to identify which of these are multiples of 7. First, we need to recall the multiplication table of 7 or check each number by dividing it by 7 to see if the result is a whole number.
Starting with the number 7, since any number is a multiple of itself, we know that 7 is a multiple of 7. The next step is to recognize if any other number in the list is a multiple of 7, which in this case, none of the remaining numbers are multiples of 7.
Therefore, the only multiple of 7 in the provided list is the number 7 itself.
It's important to practice identifying multiples, as it enhances algebraic thinking and a strong grasp of number theory, enabling simplification of algebraic expressions and better problem-solving skills in mathematics.
