9 ÷ 2 = 4.5
Therefore, 9⁄2 as a decimal is 4.5.
Step-by-Step Division Process
Let’s break down the division process step by step:
- Write down the division as 9 ÷ 2.
- Divide 9 by 2. Since 9 is greater than 2, you can divide it directly.
- The result of 9 divided by 2 is 4 with a remainder of 1.
- Place a decimal point after the 4 and add a zero to the remainder, making it 10.
- Divide 10 by 2, which gives you 5.
- Combine the whole number and the decimal part to get 4.5.
So, 9⁄2 as a decimal is 4.5.
