To express the decimal number 320.75 in expanded form, we break down each digit according to its place value:
- The digit 3 is in the hundreds place: \(3 \times 100\)
- The digit 2 is in the tens place: \(2 \times 10\)
- The digit 0 is in the ones place: \(0 \times 1\)
- The digit 7 is in the tenths place: \(7 \times 0.1\) (which is also \(7 \times \frac{1}{10}\))
- The digit 5 is in the hundredths place: \(5 \times 0.01\) (which is also \(5 \times \frac{1}{100}\))
Putting it all together, the expanded form is:
\[ (3 \times 100) + (2 \times 10) + (0 \times 1) + (7 \times 0.1) + (5 \times 0.01) \]
From the options provided, the correct answer that matches this is not explicitly stated among your options, but if we had to adapt an option, we would pick the one that follows a similar structure. However, the numerical representations of the expansion must particularly focus on the digits and the place values.
Considering the options closely, none of them accurately represent the decimal expansion as needed. In typical cases, the format should be presented as above for clarity and accuracy. In finding an option that closely represents the intended answer, please double-check the options given or modify one to suit the correct mathematical representation.
If forced to choose from the listed options, "Option not found" fits best, as none are accurate.
