Decide whether or not the number 235,950 is divisible by 30. Show or explain why.

yes it is take 30 times 7865 and you get 235950

A is divisible by B if A is divisible by all the factors of B.

30 = 2.3.5
So if 235,950 is individually divisible by 2, 3 and 5, the number is divisible by 30.

To determine if a number is divisible by 30, you need to check if it is divisible by both 2 and 5, as 30 is divisible by both 2 and 5.

First, let's check if the number is divisible by 2. A number is divisible by 2 if its last digit is even, i.e., it ends with 0, 2, 4, 6, or 8. The last digit of 235,950 is 0, which is an even number. Therefore, the number is divisible by 2.

Next, let's check if the number is divisible by 5. A number is divisible by 5 if its last digit is either 0 or 5. The last digit of 235,950 is 0, which is divisible by 5. Therefore, the number is divisible by 5.

Since the number is divisible by both 2 and 5, it is divisible by their common multiple, which is 30. Thus, the number 235,950 is divisible by 30.
