Where the decimal comes from
There is no rewrite over 10, 100 or 1000 for 2/15: 15 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:
- 20 ÷ 15 = 1remainder 5
- 50 ÷ 15 = 3remainder 5— this remainder has come around before, so from here the digits repeat
Written exactly: 0.1(3) — the parentheses mark the block that repeats forever.
