Let's solve the problem step by step.
Task:
Determine the
place value of the
underlined digit in each number.
The numbers are two-digit numbers, and the underlined digit is either in the
tens place or the
ones place.
---
Understanding Place Value:
- In a two-digit number:
- The
left digit is in the
tens place → represents how many tens.
- The
right digit is in the
ones place → represents how many ones.
For example:
- In
57, the
5 is in the tens place → it represents
50.
- The
7 is in the ones place → it represents
7.

🔍 Explanation:
All underlined digits are the
first digit in the two-digit number, which means they are in the
tens place. So their place value is that digit multiplied by 10.
For example:
- Underlined
8 in
88 → 8 × 10 =
80
- Underlined
9 in
92 → 9 × 10 =
90
So every answer is the
digit × 10.
