Most teachers will write it off as obvious. Taking a percentage of something is just multiplication and if you actually write it down with multiplication, it is, indeed, obvious:
4*75/100=75*4/100
And yes, it means you can just multiply 75 by 4 first and then divide by 100.
Why did no one ever teach me this?? Did I miss this day in class? I feel so silly. This is really useful.

Yes and no, other day I was trying to figure out 17% of a number like 65, and I’m like “Oh it’s just 65% of 17!” Which really wasn’t helpful.
It works with small numbers on one side tho.
