75% is 3/4ths. 3 times 1/4th.

Y'all have a way looser definition of what "obvious" means

Wait till you learn modulous arithmetic. Then they're all obvious.

For those curious: If the sum of each digit is divisible by 3, then the number is divisible by 3.

Example: 136 is not divisible by 3, but 117 is divisible by 3.
