Without dividing, determine if 94,725 is divisible by 6 and explain how you know.

Answer:

Is 94,725 divisible by 6?

Answer :

To determine if 94,725 is divisible by 6 without directly dividing it, we need to check two conditions:

1. The number must be divisible by 2.
2. The number must be divisible by 3.

### Step 1: Check for Divisibility by 2
A number is divisible by 2 if its last digit is even.

The last digit of 94,725 is 5, which is an odd number. Therefore, 94,725 is not divisible by 2.

### Step 2: Check for Divisibility by 3
A number is divisible by 3 if the sum of its digits is divisible by 3.

Let's sum the digits of 94,725:
[tex]\[ 9 + 4 + 7 + 2 + 5 = 27 \][/tex]

Now, we need to check if 27 is divisible by 3. Since [tex]\( 27 \div 3 = 9 \)[/tex] with no remainder, 27 is divisible by 3. Thus, 94,725 is divisible by 3.

### Conclusion:
For a number to be divisible by 6, it needs to meet both criteria (divisibility by 2 and 3). In this case:
- 94,725 is not divisible by 2.
- 94,725 is divisible by 3.

Since 94,725 does not meet both conditions, it is not divisible by 6.
