Okay, doing the math, I get the following:

76th to 72nd:

1/76 * x = 1/72
x = 1/72 / 1/76
x = 1.05555555555555555

So enlarge by 105% or 106% this will be kind of sticky, because of the
repeating 5. It is right in the middle of the two. I would tend to go
with 106% because in my experience, photocopiers tend to "shrink" copies
a fraction of a percentage each time they copy (take an image and
photocopy it, then copy the copy and so on, about 10 times to see this

By the way, the conversion the other way is .947368 so 95% reduction.
