5/4 as a Decimal
5/4 = 1.25
5/4 as a decimal is 1.25.
Step by step
- Divide 5 by 4: 1 whole, remainder 1.
- Bring down a 0: 10 ÷ 4 = 2, remainder 2.
- Bring down a 0: 20 ÷ 4 = 5, remainder 0.
- Result: 5/4 = 1.25.
Shortcut: 4 divides evenly into 100, so multiply the top and bottom by 25: 5/4 = 125/100 = 1.25. This works for any fraction whose denominator has only 2s and 5s as prime factors, which is why 5/4 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.
