Yes. If the last digit is divisible by 2 (that is if it is 0, 2, 4, 6 or 8) then the whole number is divisible by 2 and even. The last digit of 140 is 0 which is an even digit, so 140 is even.
To be divisible by a number, the result of the division by that number must be a whole number.Assuming 17.5 is divisible by 8, then 8 (a whole number) multiplied by another whole number (as required above) needs to make 17.5There are no two whole numbers that multiply together to form a non-whole number; thus 17.5 is not divisible by 8.17.5 can be divided by 8 to give 2.1875 which is not a whole number.
No, not if you want the answer to be a whole number.
If the number is even, it's divisible by 2. If the sum of the digits is a multiple of 3, the whole number is divisible by 3. If the last two digits are a multiple of 4, the whole number is divisible by 4. If the last digit is a 0 or a 5, the whole number is divisible by 5. If the number is even and divisible by 3, it's divisible by 6. If the last digit doubled subtracted from the rest is a multiple of 7, the whole number is divisible by 7. If the last three digits are a multiple of 8, the whole number is divisible by 8. If the sum of the digits is a multiple of 9, the whole number is divisible by 9. If the number ends in 0, it's divisible by 10.
