What the Symbols Mean > is greater than < is less than = is equal to

How do you compare and order whole numbers? Which is greater: 28,748 or 28,527? Line up the digits by place value. 28,748 28,527 Look at the digits from left to right. Find the first place where the digits are different. The 2’s are the same, 8’s are the same, the 7 and 5 are different. Compare the values of the digits. The numbers compare the same way. 7 hundreds > 5 hundreds

Comparing More Than Two Numbers To compare more than two numbers, use the same steps: 28,746 28,746 is the greatest number. It has the ```````most hundreds. 28,562 Then compare the other two numbers. 28,526 28,562 is greater than 28,526. It has more tens. You can write the comparison as: 28,846 is greater than 28,562 and/or 28,526. 28,846 > 28,562 28,562 is less than 28,846. 28,562 < 28,846
