## McGraw-Hill My Math Grade 4 Answer Key Chapter 1 Lesson 4 Order Numbers

Example 1

Compare the populations of the three cities and order them from greatest to least.

1. Write the populations on the place-value chart.

2. Start with the greatest place-value position. Compare.

____ > ____

3. Compare the digits in the next place.

____ = ____

4. Continue to compare until the digits are different

____ > ____

____ > ____ > ____

So, from greatest population to least, the order of the cities is

___, ____, and _____.

Answer:

Given that,

The population of Lowell is 103,299.

The population of Cambridge is 101,365.

The population of Boston is 590,763.

The greatest place value position is ten thousands place. 9 > 0

Compare the digits in the next place is 0 = 0

Compare until the digits are different is 9 > 6

7 > 3 > 2

The order of the population from greatest to least is 590,763; 103,299; 101,365.

Example 2

Order the numbers on the cards at the right from least to greatest.

1. Line up the numbers by the ones place.

Answer:

Given that,

The numbers are 245,032; 245,023; 254,002.

The order of the numbers from least to greatest is 245,023; 245,032; 254,002.

2. Start with the greatest place-value position. Compare.

Each number has a ____ in the hundred thousands place. So, compare the digits in the ten thousands place. The greatest number is _____

The two numbers that are left both have a ___ in the thousands place and a ___ in the hundreds place. The second greatest number is ____

So, in order from least to greatest, the numbers are

_____________________

Answer:

Each number has a 2 in the hundred thousands place. So, compare the digits in the ten thousands place. The greatest number is 254,002

The two numbers that are left both have a 5 in the thousands place and a 0 in the hundreds place. The second greatest number is 245,032

So, in order from least to greatest, the numbers are 245,023; 245,032; 254,002.

**Talk Math**

When ordering numbers, what do you do when the digits in the same place have the same value?

Answer:

When the digits in the same place have the same value means that both numbers are equal.

You cannot order the numbers.
