If a number is divided by 12 and gives a remainder of 7, what will be the remainder when the same number is divided by 3? (2023)
Step 1: Understand that when a number is divided by 12 and gives a remainder of 7, it can be written in the form of 12k + 7, where k is any whole number.
Step 2: To find the remainder when this number (12k + 7) is divided by 3, we can break it down into two parts: 12k and 7.
Step 3: Calculate the remainder of 12k when divided by 3. Since 12 is a multiple of 3, 12k will give a remainder of 0.
Step 4: Now, calculate the remainder of 7 when divided by 3. When you divide 7 by 3, the remainder is 1 (because 7 = 3 * 2 + 1).
Step 5: Combine the remainders from Step 3 and Step 4. The total remainder when 12k + 7 is divided by 3 is 0 + 1, which equals 1.
