I was helping my little brother with math homework (maybe 3rd grade?) and he had gotten a question on it wrong because he wrote 1/2 and the teacher said the answer was 5/10… I emailed his teacher and she insisted that the two fractions weren’t equivalent. After explaining that one can simplify fractions, her mind was blown. This was a teacher at a public school.
