Key Points to Remember

Essential concepts to master this topic
  • Place Value Rule: The tens digit is the second digit from the right
  • Technique: In 883, identify positions: hundreds (8), tens (8), ones (3)
  • Check: Compare tens digit to 7: is 8 > 7? Yes! ✓

Common Mistakes

Avoid these frequent errors
  • Confusing tens digit with hundreds digit
    Don't look at the first digit in a 3-digit number as the tens place = wrong digit analyzed! The first digit is hundreds, not tens. Always count positions from right to left: ones, tens, hundreds.

FAQ

Everything you need to know about this question

How do I remember which digit is the tens place?

+

Think of it as counting from right to left: ones place (1st), tens place (2nd), hundreds place (3rd). The tens digit is always the middle digit in a 3-digit number!

What does 'greater than 7' mean exactly?

+

Greater than 7 means the digit must be 8 or 9 only. Numbers like 7 are equal to 7, not greater than 7, so they don't count!

Why isn't 978 correct if it has an 8?

+

Look carefully at the position! In 978, the 8 is in the ones place, not the tens place. The tens digit is 7, which is not greater than 7.

Can I use this method for 4-digit numbers too?

+

Absolutely! Just remember the pattern: ones, tens, hundreds, thousands. Count from right to left, and the tens place is always the 2nd position from the right.

What if two numbers both have tens digits greater than 7?

+

Then both would be correct answers! In this problem, only 883 883 has a tens digit (8) greater than 7, making it the only right choice.
