How to convert this fraction
Divide 9 by 2 using integer long division. The whole-number part is 4; the remaining fraction is 1/2.
- Bring down a zero: remainder × 10 gives the next decimal digit 5; the new remainder is 0.
The remainder reaches zero after 1 decimal places, so 9/2 = 4.5 exactly.
As a mixed-number decomposition: 9/2 = 4 + 1/2.
Check: 4 × 2 + 1 = 9, so the quotient and remainder reconstruct the original fraction.
