Answer 1

To express the number 320.75 in expanded form using decimal expansion, we need to identify the place value of each digit.

For 320.75:
- The "3" is in the hundreds place.
- The "2" is in the tens place.
- The "0" is in the units place.
- The "7" is in the tenths place (1/10).
- The "5" is in the hundredths place (1/100).

Thus, the correct expanded form can be written as:

\[
(3 \times 100) + (2 \times 10) + (0 \times 1) + (7 \times \frac{1}{10}) + (5 \times \frac{1}{100})
\]

Now, looking at the options provided, the correct answer is:

**(3×100)+(2×10)+(0×1)+(7×1/10)+(5×1/100)**
open paren 3 times 100 close paren plus open paren 2 times 10 close paren plus open paren 0 times 1 close paren plus open paren 7 times 1 over 10 close paren plus open paren 5 times 1 over 100 close paren.
