Subject: mental gymnastics

There are some "mental gymnastics" in the NJSTA newsletter that I use in
my science club. Most answers are "scientific." For example:

5280 = F in a M (feet in a mile)

7 PC in L (primary colors in light)


A few have stumped me:

70/PGR = DT

1/127 = A

Anyone know what those letters stand for?
