In this worksheet, you have to place large numbers in ascending (increasing) order of size.

Numbers will be no larger than 10 million (10 000 000).

In this worksheet, we will group digits in threes, leaving spaces between each group.

4 578 025 is the number 4 million, 578 thousand, and 25.

When you compare two numbers, think of placing each digit into the usual columns.

Then start comparing the digits in each column **from the left**.

If the digits match in the column you are comparing, you must move one column to the right and compare those digits.

__Example 1__

Place in ascending order:

**4 146 302, 4 145 984** and **5 110 243**

**Answer**

When placed in columns, we can compare the millions columns.

The number with 5 million is the largest, so this will go last.

Compare the two numbers beginning with 4 million.

The smaller of the two is 4 145 984. (The first three digits match, so compare the thousands column.)

**1 (smallest)**** 4 145 984 **

**2 4 146 302 **

**3 (largest) 5 110 243**
