The underlined digit is in the hundreds place, so it equals 9 hundreds.

So, the value of the underlined digit is 900.

The underlined digit is in the hundredths place, so it equals 8 hundredths.

So, the value of the underlined digit is 0.08.

The 7 in the ten thousands place has a value of 70,000.
The 7 in the thousands place has a value of 7,000.

So, 70,000 is ten times greater than 7,000.
This means that the 7 in the ten thousands place is ten times greater than the 7 in the thousands place.

The 7 in the tens place has a value of 70.
The 7 in the hundreds place has a value of 700.

So, 70 is one-tenth of 700.
The 7 in the tens place is one-tenth of the 7 in the hundreds place.

First, identify the value of each digit in the number based on its place value.

The 8 in the hundred thousands place represents 8 hundred thousands.
So, the value of the 8 in the hundred thousands place is 800,000.

The 5 in the ten thousands place represents 5 ten thousands.
So, the value of the 5 in the ten thousands place is 50,000.

The 5 in the thousands place represents 5 thousands.
So, the value of the 5 in the thousands place is 5,000.

The 8 in the hundreds place represents 8 hundreds.
So, the value of the 8 in the hundreds place is 800.

The 7 in the tens place represents 7 tens.
So, the value of the 7 in the tens place is 70.

The 4 in the ones place represents 4 ones.
So, the value of the 4 in the ones place is 4.

Then, write the values as a sum to write the number in expanded notation.

Find the sum to write the number in standard notation.

Multiply each digit by its place value.

The value of the 1 in the hundreds place is 1 × 100.
The value of the 1 in the tens place is 1 × 10.
The value of the 8 in the ones place is 8 × 1.
The value of the 4 in the tenths place is 4 × $\frac{1}{10}$.
The value of the 4 in the hundredths place is 4 × $\frac{1}{100}$.

So, the number in expanded notation is
1 × 100 + 1 × 10 + 8 × 1 + 4 × $\frac{1}{10}$ + 4 × $\frac{1}{100}$.
