Interpreting .875 as 7/8 -
On any tape measure or ruler, .875 corresponds to the 7th mark in an 8-division scale, so .875″ = 7/8″; this trick is outlined in the Journal of Engineering Measurements. Spotting "875 on a ruler" becomes intuitive once you visualize eight equal spaces.
Timed Practice and Mnemonics -
Boost speed and retention with a quick online tape measure test or ruler quiz from the University of Minnesota's Geometry Center; set a timer to simulate real-world tasks. Employ mnemonic devices like "ice-cream trick" (longest lick = largest fraction) to recall smaller divisions.
