Question

7.9

Answer 1

To determine the decimal expansion of 7.9 using long division, we will perform the division of 7.9 by 1.

Here's how the calculation works:

1. Divide 7 by 1:

   • 7 divided by 1 equals 7.

2. Bring down the decimal:

   • After 7, we have a decimal point. At this point, we look at the next number, which is 9 (from 7.9).

3. Divide 9 by 1:

   • 9 divided by 1 equals 9.

4. Combine the results:

   • So, 7.9 divided by 1 gives us the result of 7.9.

Since we are splitting 7.9 into its decimal form, the decimal representation already is 7.9.

Thus, the decimal expansion of 7.9 is:

\[ 7.9 \]
