Where the decimal comes from
There is no rewrite over 10, 100 or 1000 for 5/12: 12 has a prime factor other than 2 and 5, so no whole-number multiplier reaches a power of ten. Watch the long division to see what happens instead — the remainders start circling, and once a remainder comes back, the digits must too:
- 50 ÷ 12 = 4remainder 2
- 20 ÷ 12 = 1remainder 8
- 80 ÷ 12 = 6remainder 8— this remainder has come around before, so from here the digits repeat
Written exactly: 0.41(6) — the parentheses mark the block that repeats forever.
