Chapter 1: Problem 75

Fill in the blank with the inequality symbol \(<\) or \(>\). $$21 \square 18$$

Short Answer

Expert verified
21 > 18

Step by step solution

01

Understand the Symbols

The symbols to use are the inequality symbols, which are < (less than) and > (greater than).
02

Compare the Numbers

Compare the two given numbers, 21 and 18. Determine which number is larger and which is smaller.
03

Apply the Correct Symbol

Since 21 is greater than 18, the correct inequality symbol to fill in the blank is >.

Key Concepts

These are the key concepts you need to understand to accurately answer the question.

Less than symbol
In mathematics, we frequently use the less than symbol < to compare two numbers. When we use <, we are saying that one number is smaller than another.
The symbol < looks like an arrowhead pointing to the left.
For example, if we compare 3 and 7, we write 3 < 7 because 3 is less than 7.
Anytime the left number is smaller, you use <.
Here's another example: 10 < 15 means 10 is less than 15.
Remember, the small end of the symbol points to the smaller number.
Greater than symbol
The greater than symbol > is used to show that one number is larger than another.
This symbol > looks like an arrowhead pointing to the right.
For instance, if we compare 9 and 4, we write 9 > 4 because 9 is greater than 4.
Whenever the left side number is bigger, use >.
Here's another illustration: 14 > 8 means 14 is greater than 8.
The wide part of the symbol always opens toward the larger number.
This makes it easier to visually remember how to use it.
Comparing numbers
When comparing numbers, we determine which number is bigger or smaller. This helps us decide which inequality symbol to use.
Take any two numbers and check their size. If the first number is smaller, use <. If bigger, use >.
For example, if you have 21 and 18, you need to compare them. Since 21 is larger than 18, you use the > symbol. Therefore, 21 > 18.
Once you understand how to compare, filling in blanks with the correct symbol becomes straightforward.
Always remember to evaluate carefully to correctly decide between < and >.
