21/2 as a decimal

Answer

21/2 in decimals can be written as 10.5. This is a terminating decimal, meaning it ends and does not repeat infinitely.

Explanation

To convert 21/2 into a decimal, we will use the division method. Here, as 21 is greater than 2, we can divide directly. Let's see the step-by-step breakdown of the process:

Step 1: Identify the numerator and denominator because the numerator (21) will be taken as the dividend and the denominator (2) will be taken as the divisor.

Step 2: Divide 21 by 2.

Step 3: 2 goes into 21 ten times, which gives us 20. Write 10 in the quotient place.

Step 4: Subtract 20 from 21, which leaves a remainder of 1.

Step 5: Bring down a 0 to make it 10. Now divide 10 by 2, which gives 5.

Step 6: Write 5 in the quotient place, making it 10.5. The division process ends here as we have a remainder of 0.

The answer for 21/2 as a decimal is 10.5.
