Work Step by Step
Let's look at the process of writing whole numbers in standard form in more detail.
Standard form for whole numbers refers to writing the number using digits, with commas separating the digits into groups of three, starting from the right.
The reason for this format is to make the numbers easier to read and understand. Grouping the digits into threes helps to quickly identify the place value of each digit.
For example, let's look at the first part of the question:
a) Forty-two thousand, three hundred and sixty-five
To write this in standard form:
- Identify the place value of each part of the number:
- Forty-two thousand
- Three hundred
- Sixty-five
- Write the digits in the correct order, with commas separating the groups of three:
- 42,365
The same process applies to the other numbers in the question:
b) Nine hundred and seven
- The digits are 9, 0, and 7
- Written in standard form: 907
c) Six million, two hundred and forty-four thousand, one hundred and three
- The digits are 6, 244, 103
- Written in standard form: 6,244,103
The key things to remember are:
1. Identify the place value of each part of the number
2. Write the digits in the correct order
3. Use commas to separate the digits into groups of three
This ensures the whole number is represented accurately and clearly in standard form.
