3/10 = 0.3

3/10 as a decimal is 0.3.

Step by step

  1. Divide 3 by 10: 0 whole (so the answer starts 0.), remainder 3.
  2. Bring down a 0: 30 ÷ 10 = 3, remainder 0.
  3. Result: 3/10 = 0.3.

Shortcut: 10 divides evenly into 10, so multiply the top and bottom by 1: 3/10 = 3/10 = 0.3. This works for any fraction whose denominator has only 2s and 5s as prime factors, which is why 3/10 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.
