The correct expanded form of 357.25 is:
\[ (3 \times 100) + (5 \times 10) + (7 \times 1) + (2 \times \frac{1}{10}) + (5 \times \frac{1}{1000}) \]
To clarify, the components break down as follows:
- 3 represents 300 (3 times 100)
- 5 represents 50 (5 times 10)
- 7 represents 7 (7 times 1)
- 2 represents 0.2 (2 times 1/10)
- 5 represents 0.005 (5 times 1/1000)
So the correct answer from the options provided is:
(3×100)+(5×10)+(7×1)+(2×\frac{1}{10})+(5×\frac{1}{1000}).
