represent the value of the digit in decimals through the thousandths using expanded notation and numerals;
Florida - Benchmarks for Excellent Student Thinking: MA.5.NSO.1.1
Express how the value of a digit in a multi-digit number with decimals to the thousandths changes if the digit moves one or more places to the left or right.

Compose and decompose multi-digit numbers with decimals to the thousandths in multiple ways using the values of the digits in each place. Demonstrate the compositions or decompositions using objects, drawings and expressions or equations.

Expanded notation is a way to write a number as the
sum of the value of each digit based on 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}

.
The value of the 6 in the thousandths place is 6 ×

\frac{1}{1,000}

So, the number in expanded notation is
1 × 100 + 1 × 10 + 8 × 1 + 4 ×

\frac{1}{10}

+ 4 ×

\frac{1}{100}

+ 6 ×

\frac{1}{1,000}

2 × 100 = 200

8 × 10 = 80

6 × 1 = 6

9 ×

\frac{1}{10}

= 0.9

2 ×

\frac{1}{100}

= 0.02

8 ×

\frac{1}{1,000}

= 0.008
