Use decimal expansion to write 320.75 in expanded form.(1 point)
320.75 = 3*100 + 2*10 + 0*1 + 7*(1/10) + 5*(1/100)
31,476.52 = 3*10,000 + 1*1,000 + 4*100 + 7*10 + 6*1 + 5*(1/10) + 2*(1/100)
7,921.995 = 7*1,000 + 9*100 + 2*10 + 1*1 + 9*(1/10) + 9*(1/100) + 5*(1/1,000)

To write 320.75 in expanded form using decimal expansion, we need to break down the number into its place values.
320 is in the hundreds place, 0 is in the tens place, and 7 is in the ones place. So, we can write 320 as:
300 + 20 + 0
0.75 is in the tenths and hundredths place. So, we can write 0.75 as:
0.7 + 0.05
Combining these values, we can write 320.75 in expanded form as:
300 + 20 + 0 + 0.7 + 0.05
To write a decimal number in expanded form, we need to break it down into its place values. Let's look at the given number, 320.75:
- The digit in the hundreds place is 3, so we have 3 * 100 = 300.
- The digit in the tens place is 2, so we have 2 * 10 = 20.
- The digit in the units (ones) place is 0, so we don't include anything for this place value.
- The digit in the tenths place is 7, so we have 7 * 0.1 = 0.7.
- The digit in the hundredths place is 5, so we have 5 * 0.01 = 0.05.
Adding all these values together, we get:
300 + 20 + 0 + 0.7 + 0.05 = 320.75
Therefore, the expanded form of 320.75 is:
300 + 20 + 0 + 0.7 + 0.05.
