Order the following numbers from least to greatest.

In this question, we’re comparing three four-digit numbers. We have to order these three numbers from the least to the greatest. Let’s compare our numbers using the place value chart. Our first four-digit number has one 1,000, no 100s, nine 10s, and no ones. The number is 1,090. Our second four-digit number also has one 1,000. It has one 100, nine 10s, and no ones. And our third four-digit number also has one 1,000. It has no 100s, no 10s, and nine ones.

Which of our three four-digit numbers is worth the least? Let’s start by comparing the thousands digits. Each of our numbers has the same amount of thousands. They all have a one digit in the thousands column, so we need to compare the hundreds digits. The number 1,090 has no 100s, and the number 1,009 also has no 100s. But 1,190 has one 100, so we know this is the greatest number. Let’s cross that number out. Now we can compare our two remaining numbers. We need to compare the tens digit. 1,090 has nine 10s, and 1,009 has no tens, so we know 1,090 is worth more than 1,009.

We compared the value of the thousands, hundreds, and tens digits and ordered the numbers from least to greatest. The correct order is 1,009, 1,090, and 1,190.
