minus-squarewumpoooo@lemmy.worldlinkfedilinkarrow-up2·1 year agoMaybe a stupid question, but can you even divide a number with infinite decimals? I know you can find ratios of other infinitely repeating numbers by dividing them by 9,99,999, etc., divide those, and then write it as a decimal. For example 0.17171717…/3 (17/99)/3 = 17/(99*3) = 17/297 but with 9 that would just be… one? 9/9=1 That in itself sounds like a basis for a proof but idk
minus-squarequicksand@lemmy.worldlinkfedilinkarrow-up2·1 year agoYes that’s essentially the proof I learned in high school. 9/9=1. I believe there’s multiple ways to go about it.
