9/10 as a Decimal
9/10 = 0.9
9/10 as a decimal is 0.9.
Step by step
- Divide 9 by 10: 0 whole (so the answer starts 0.), remainder 9.
- Bring down a 0: 90 ÷ 10 = 9, remainder 0.
- Result: 9/10 = 0.9.
Shortcut: 10 divides evenly into 10, so multiply the top and bottom by 1: 9/10 = 9/10 = 0.9. This works for any fraction whose denominator has only 2s and 5s as prime factors, which is why 9/10 gives a terminating decimal.

How it works
A fraction means division: the numerator (top) divided by the denominator (bottom). Use long division, adding zeros after the decimal point until the remainder is zero or a remainder repeats. If the simplified denominator has only 2 and 5 as prime factors, the decimal terminates; otherwise it repeats forever, and the repeating digits are marked with a bar.
