## Texas Go Math Grade 5 Lesson 1.3 Answer Key Place Value of Decimals

**Unlock the Problem**

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.

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.

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

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 formÂ means writing the numberÂ 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 isÂ 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 Ã— 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 spiderâ€™s silk.

So,

The thickness of the garden spiderâ€™s silk is 0.01 times that of the thread.
