Answer 1

To express the number 7,921.995 in expanded form, we break it down by each digit according to its place value.

7,921.995 can be expressed as:

- 7 thousands (7 × 1,000)
- 9 hundreds (9 × 100)
- 2 tens (2 × 10)
- 1 one (1 × 1)
- 9 tenths (9 × 0.1)
- 9 hundredths (9 × 0.01)
- 5 thousandths (5 × 0.001)

Putting this all together, the expanded form is:

**(7 × 1,000) + (9 × 100) + (2 × 10) + (1 × 1) + (9 × 0.1) + (9 × 0.01) + (5 × 0.001)**

This is equivalent to selecting:

**(7×1,000) + (9×100) + (2×10) + (1×1) + (9×1/10) + (9×1/100) + (5×1/1,000)**

So the correct answer from your options is:

**(7×1,000) + (9×100) + (2×10) + (1×1) + (9×1/10) + (9×1/100) + (5×1/1,000)**
