Is 91 a multiple of 13?
The correct answer and explanation is:
No, 91 is not a multiple of 13.
To determine if 91 is a multiple of 13, divide 91 by 13. If the result is a whole number, then 91 is a multiple of 13. When dividing 91 by 13: 91÷13=791 ÷ 13 = 7
The quotient is 7, which is an integer. This means that 91 is divisible by 13, and 91 can be expressed as: 91=13×791 = 13 × 7
This confirms that 91 is, in fact, a multiple of 13. A number is a multiple of another number if, when divided, the remainder is zero. Since the division of 91 by 13 results in an integer without a remainder, it is a multiple.
The concept of multiples can be understood as numbers that result from multiplying an integer by another integer. For example, multiples of 13 include numbers like 13, 26, 39, 52, 65, 78, 91, 104, and so on. These numbers all come from multiplying 13 by different whole numbers.
In summary, 91 is a multiple of 13 because when divided by 13, the result is a whole number (7), and there is no remainder. The division process shows that 91 is exactly divisible by 13, verifying that it is indeed a multiple of 13.
