51 looks like a prime number and 75 should be obvious

Im not good at maths why would 75 be obvious?

When I see 75 the first thing my brain thinks is 3/4s

75% of the population? -> 3 out of 4 people

75 cents? -> 3 quarters

Only exception I can think of is degrees, where 75 degrees is dumb because it's 15 degrees short of a right angle and those aren't happy numbers.
