The Brooklyn Battery Tunnel in New York City is 1.726 miles long. It is the longest underwater tunnel for vehicles in the United States. To understand this distance, you need to understand the place value of each digit in 1.726.
Texas Go Math Grade 5 Lesson 1.3 Answer Key 1
You can use a place-value chart to understand decimals. Whole numbers are to the left of the decimal point. Decimals are to the right of the decimal point. The thousandths place is to the right of the hundredths place.
Texas Go Math Grade 5 Lesson 1.3 Answer Key 2
The place value of the digit 6 in 1.726 is thousandths. The value of 6 in 1.726 is 6 \(\frac{1}{1,000}\) or 0.006.
Standard Form: 1.726
Word Form: one and seven hundred twenty-six thousandths
Expanded Form: 1 + 0.7 + 0.02 + 0.006

Explain how the value of the last digit in a decimal can help you read a decimal.
Answer:
We know that,
Values to the left of the decimal point are greater than one.
Now,
38 means 3 tens and 8 ones.
The word name of the decimal is determined by the place value of the digit in the last place.
Ex:
In 1.3215,
The last digit (5) is in the ten-thousandth place

Use place value to read and write decimals.

A. Standard Form: 2.35
Word Form: two and ____________
Expanded Form: 2 + ___________
Answer:
The given standard form is: 2.35
Now,
We know that,
Expanded form means writing the number so you show the value of each digit. Word form means writing the number with words instead of numerals
So,
The word from of 2.35 is: Two and Thirty-five hundredths
The Expanded form of 2.35 is: 2 + 0.3 + 0.05
Hence, from the above,
We can conclude that
The word from of 2.35 is: Two and Thirty-five hundredths
The Expanded form of 2.35 is: 2 + 0.3 + 0.05

B. Standard Form: ____________
Word Form: three and six hundred fourteen thousandths
Expanded Form: ____________ + 0.6 + ____________ + ____________
Answer:
The given word form is: Three and six hundred fourteen thousandths
Now,
We know that,
The standard form is the combination of digits written together as a single number. In the expanded form the digits of the number are split into each of the individual digits with their place value and written in expanded form
So,
The standard form of the given word form is: 3.614
The expanded form of the given word form is: 3 + 0.6 + 0.01 + 0.004
Hence, from the above,
We can conclude that
The standard form of the given word form is: 3.614
The expanded form of the given word form is: 3 + 0.6 + 0.01 + 0.004

Example

Use place value to compare.
The silk spun by a common garden spider is about 0.003 mm thick. A commonly used sewing thread is about 0.3 mm thick. How does the thickness of the spider silk and the thread compare?
Count the number of decimal place-value positions to the digit 3 in 0.3 and 0.003.
0.3 has 2 fewer decimal places than 0.003
2 fewer decimal places: 10 × 10 = 100
So,
0.3 is 100 times as much as 0.003
0.003 is 0.01 of 0.3
So, the thread is 0.01 times as thick as the garden spider’s silk.
So,
The thickness of the garden spider’s silk is 0.01 times that of the thread.
