To convert the whole number 1230 to a decimal, we need to divide it by 1000.

Performing the long division:

  1. 1230 divided by 1000:

    • 1000 goes into 1230 once (1).
    • 1 * 1000 = 1000
    • Subtract 1000 from 1230, which leaves us with 230.
  2. We then bring down two zeros from the decimal point (making it 23000):

    • 1000 goes into 2300 two times (2).
    • 2 * 1000 = 2000
    • Subtract 2000 from 2300, leaving us with 300.
  3. Bring down another zero making it 3000:

    • 1000 goes into 3000 three times (3).
    • 3 * 1000 = 3000
    • Subtract 3000 from 3000, leaving us with 0.

So, the division gives us:

1230 รท 1000 = 1.230 or 1.23 as a decimal.

To express 1230 as a decimal without the divisor being explicitly stated, it is equivalent to:

12.3 when considering the multiplication by \(10\).

Based on the responses, the correct conversion of 1230 would be 12.3.
