42000 In Words
In this lesson, we will learn how to express the number 42000 in words. This is an important skill to have, as it allows us to read and understand large numbers as words. The ability to express numbers in words is useful in a variety of situations, such as writing checks, reading financial reports, and understanding numerical quantities in literature or scientific texts.
To express 42000 in words, we will break down the number into its individual place values and then assign words to each place value. Let's go through the step-by-step process:
Step 1: Understand Place Values
Before we begin, let's review the concept of place values. In our number system, each digit in a number represents a specific place value. The place values are powers of 10, starting from the rightmost digit.
For example, in the number 42000, the digit '2' represents the thousands place value, '4' represents the ten thousands place value, and '0' represents the units and hundreds place values.
| Place Value | Ten Thousands | Thousands | Units | Hundreds |
|---|---|---|---|---|
| Digit | 4 | 2 | 0 | 0 |
Step 2: Express Each Digit in Words
Now that we understand the place values, let's express each digit in words.
The ten thousands place is represented by the digit '4'. In words, we would say this as "forty thousand."
The thousands place is represented by the digit '2'. In words, we would say this as "two thousand."
The units and hundreds place are represented by the digits '0'. Since both digits are zero, we don't need to include them in our word expression.
| Place Value | Ten Thousands | Thousands | Units | Hundreds |
|---|---|---|---|---|
| Digit | 4 | 2 | 0 | 0 |
| Word | forty | two |
Step 3: Combine the Words
Now that we have expressed each digit in words, we can combine them to form our final expression for 42000.
| Place Value | Ten Thousands | Thousands | Units | Hundreds |
|---|---|---|---|---|
| Digit | 4 | 2 | 0 | 0 |
| Word | forty | two |
Putting it all together, we can express 42000 in words as "forty-two thousand."
42000 in Words: forty-two thousand
