What is a number between 50 to 70 and divisible by 3 and 5
To be divisible by both 3 and 5, the number must be divisible by 15
What are the multiples of 15 between 50 and 70?
The first 3 are 15, 30, 45, so .....
To find a number between 50 and 70 that is divisible by both 3 and 5, we can follow these steps:
Step 1: Identify the multiples of 3 between 50 and 70.
The multiples of 3 between 50 and 70 are: 51, 54, 57, 60, 63, 66, and 69.
Step 2: Identify the multiples of 5 between 50 and 70.
The multiples of 5 between 50 and 70 are: 50, 55, 60, and 65.
Step 3: Identify the common multiples of 3 and 5.
The common multiples of 3 and 5 between 50 and 70 are: 60.
Therefore, the number that satisfies the given criteria (between 50 and 70, divisible by 3 and 5) is 60.
To find a number between 50 and 70 that is divisible by both 3 and 5, we can follow these steps:
1. Determine the range: We are looking for a number between 50 to 70, inclusively. So, the numbers in the range are 50, 51, 52, ..., 69, 70.
2. Identify divisible numbers: Among the numbers in the range, we need to find the ones that are divisible by both 3 and 5. A number is divisible by 3 if the sum of its digits is divisible by 3. A number is divisible by 5 if the ones digit is either 0 or 5.
3. Check each number: Starting from 50, we can check each number in the range to see if it satisfies both conditions. Since we are looking for the smallest number in the range, we can start from the lowest number and increment by 1 until we find a number that meets both conditions.
Using this approach, we can determine that the number between 50 and 70 that is divisible by both 3 and 5 is 60.
