To express 90.125 in expanded form, we break it down by place value:
- The digit '9' is in the tens place, so it represents \(9 \times 10\).
- The digit '0' is in the ones place, so it represents \(0 \times 1\).
- The digit '1' is in the tenths place, so it represents \(1 \times \frac{1}{10}\).
- The digit '2' is in the hundredths place, so it represents \(2 \times \frac{1}{100}\).
- The digit '5' is in the thousandths place, so it represents \(5 \times \frac{1}{1000}\).
Putting it all together, the correct expanded form of 90.125 is:
\[ 9 \times 10 + 0 \times 1 + 1 \times \frac{1}{10} + 2 \times \frac{1}{100} + 5 \times \frac{1}{1000} \]
However, since the option selections do not include \(0 \times 1\) (it may not be necessary if we just focus on the non-zero values), the most fitting option in your responses is:
9 × 10 + 1 × 1/10 + 2 × 1/100 + 5 × 1/1000
So, the final answer for Part A is:
9 × 10 + 1 × 1/10 + 2 × 1/100 + 5 × 1/1000
Now, please provide the question for Part B.
