Solving for a Number Divisible by 2

To find a number that is divisible by 2, we need to substitute the asterisk in the number 251* with a digit that makes the resulting number divisible by 2.

Step 1: Identify the Options We have the following options for the digit to substitute in place of the asterisk: 0, 2, 4, 6, or 8.

Step 2: Testing the Options Let's test each option to see which one results in a number that is divisible by 2.

- 2510 is divisible by 2 because 10 is divisible by 2. - 2512 is not divisible by 2 because 12 is not divisible by 2. - 2514 is not divisible by 2 because 14 is not divisible by 2. - 2516 is divisible by 2 because 16 is divisible by 2. - 2518 is not divisible by 2 because 18 is not divisible by 2.

Step 3: Conclusion From the options tested, 2510 and 2516 are the numbers that, when substituted for the asterisk, result in a number that is divisible by 2.

Therefore, the numbers that can be substituted in place of the asterisk to make the resulting number divisible by 2 are 0 and 6.
