If a number is divided by 15 and leaves a remainder of 10, what will be the remainder when this number is divided by 5? (2023)
Step 1: Understand that when a number is divided by 15 and leaves a remainder of 10, it can be expressed as: number = 15k + 10, where k is some integer.
Step 2: We need to find the remainder when this number (15k + 10) is divided by 5.
Step 3: Break down the expression: 15k is divisible by 5, so it leaves a remainder of 0 when divided by 5.
Step 4: Now, consider the remainder of 10 when divided by 5.
Step 5: Divide 10 by 5. The result is 2 with a remainder of 0.
Step 6: Combine the results: Since 15k gives a remainder of 0 and 10 gives a remainder of 0, the total remainder when the number is divided by 5 is 0.
