In 52469, 6 is in the (a) ones period (c) thousands period (b) hundreds period
The correct answer and explanation is:
Correct Answer: (a) ones period
Explanation:
To determine which period a digit belongs to in a number, we must understand how numbers are grouped in place value:
Periods in place value refer to groups of three digits, starting from the right. In large numbers, each period is separated by a comma for easier reading. The standard periods in place value (for whole numbers) are:
- Ones Period: includes ones, tens, hundreds
- Thousands Period: includes thousands, ten-thousands, hundred-thousands
- Millions Period, and so on.
Let’s break down the number 52,469 by place value:
| Place | Digit |
|---|---|
| Ten-thousands | 5 |
| Thousands | 2 |
| Hundreds | 4 |
| Tens | 6 |
| Ones | 9 |
Now group them by periods:
- Thousands Period: 52 → includes digits in the ten-thousands (5) and thousands (2) places
- Ones Period: 469 → includes digits in the hundreds (4), tens (6), and ones (9) places
The digit in question is 6. As shown, the 6 is in the tens place. The tens place is part of the ones period (not to be confused with the ones place specifically, which only refers to the last digit).
Summary:
- The number 52,469 is made up of two periods: thousands and ones.
- The digit 6 is in the tens place, which falls under the ones period.
- Therefore, the correct answer is: (a) ones period.
