How it works
To find the decimal representation of the fraction 4/3, divide the numerator by the denominator:
Division Formula
4 ÷ 3 = 1.3̄
Decimal Type
This is a repeating decimal, which means the decimal values loop infinitely. It is commonly written with a bar over the repeating portion: 1.3̄ (or rounded to 1.333).
Step-by-Step Division for 4/3
To perform this conversion manually, use long division. Treat the fraction line as a division symbol:
1. 1 divided by 12 (or 4 by 3) is calculated via long division.
2. Keep performing division to spot the repeating loop pattern.
3. The value 3 repeats infinitely, yielding 1.3̄.
Terminating vs. Repeating Decimals
Fractions whose denominators only have prime factors of 2 or 5 will always result in a terminating decimal (like 1/2, 1/4, or 1/5). Denominators with other prime factors (like 3 or 12) result in repeating decimal sequences.
