The following question has two parts. First, answer part A. Then, answer part B. In math class, Alyssa's average test score is 90.125. Part A What is 90.125 written in expanded form? (1 point) Responses 9×10+1×1+2×1/10+5×1/100 9 × 10 + 1 × 1 + 2 × 1 10 + 5 × 1 /100 9×1+1×1/10+2×1/100+5×11,000 9 × 1 + 1 × 1 10 + 2 × 1 100 + 5 × 1 /1 , 000 9×10+1×1/10+2×1/100+5×11,000 9 × 10 + 1 × 1 10 + 2 × 1/ 100 + 5 × 1 1 , 000 9×1+1×1/100+2×11,000+5×1/10,000

1 answer

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.
