Hi everyone! I’m new here, but that is beside the point. I had a similar question regarding 一つ.

On the kanji page for 一, 一つ’s written pronunciation is ひとつ, but the audio seems to say すとつ. Ive looked for the answer online, but I have found both pronunciations. Can someone please clarify what is going on here, and when each should be used.

Thanks!
