Ah, yaar, my daughter actually taught me this! If the denominator after simplifying can be written as only 2's and 5's, it's terminating. Here, 3125 is 5⁵, so yes—13/3125 will terminate. My life lesson? I regret ignoring my teacher, now I'm the student paying school fees to learn from my own child's homework!
