Explain how to compare 3-digit numbers

Prompt PPJ-MTH-01256

🦉 Learn it

To compare two three-digit numbers, look at the hundreds first. More hundreds means a bigger number.

If the hundreds are the same, look at the tens. If the tens are the same too, look at the ones.

Never start with the ones. A number with big ones can still be smaller.

652 and 625

Hundreds: 6 and 6, the same.

Tens: 5 and 2. 5 tens is more.

So 652 is greater than 625.
