A number is divisible by 12. By what other numbers will that number be...
To determine the numbers by which a given number will be divisible, we need to consider the factors of that number. In this case, we are given that the number is divisible by 12.
Factors of 12:
The factors of 12 are the numbers that divide 12 without leaving a remainder. These factors are 1, 2, 3, 4, 6, and 12.
Divisibility by 3:
To determine if a number is divisible by 3, we need to check if the sum of its digits is divisible by 3. In the case of 12, the sum of its digits (1 + 2) is 3, which is divisible by 3. Therefore, 12 is divisible by 3.
Divisibility by 4:
To determine if a number is divisible by 4, we need to check if the last two digits form a number that is divisible by 4. In the case of 12, the last two digits are 12 itself, which is divisible by 4. Therefore, 12 is divisible by 4.
So, the numbers by which 12 will be divisible are 1, 2, 3, 4, 6, and 12.
Out of the given options, the correct answer is option 'D' (3 and 4) because both 3 and 4 are factors of 12.
A number is divisible by 12. By what other numbers will that number be...
12÷ 4 = 3
12÷3 = 4
4× 3 =12
3×4 = 12
so the answer is d) 3 and 4
