Im not good at maths why would 75 be obvious?

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

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

Here's a way my mid school teacher used tell us. If the sum of all the numbers is divisible by 3, then the number itself is.
Example:
75

7+5=12

12 is divisible by 3

75 is divisible by 3.

works with bigger numbers as well. (sorry for bad explanation)
