Chapter 1: Problem 83

Fill in the blank with the inequality symbol $<$ or $>$. $$90 \square 91$$

Short Answer

Expert verified

90 < 91

Step by step solution

Understand the Given Numbers

The numbers given are 90 and 91. It is important to recognize the relationship between these numbers.

Compare the Two Numbers

Since 91 is one more than 90, 90 is less than 91.

Choose the Correct Inequality Symbol

The correct inequality symbol to use between 90 and 91 is the less than symbol.

Fill in the Blank

Replace the square with the less than symbol, completing the inequality as follows: $$90 < 91.$$

Comparison of Numbers

Comparing numbers is a fundamental math skill that allows us to determine the relative size of numbers. When we compare two numbers, we want to see which one is bigger, smaller, or if they are equal. This is done using inequality symbols. Let's look at an example with 90 and 91.
First, we need to understand the values. 90 is a number that is smaller than 91 by just one unit.
When comparing these numbers, we place them side by side and decide if one is less than, greater than, or equal to the other.

Less Than Symbol

The less than symbol (\textless) is used when one number is smaller than another number. It points to the smaller number. In the context of the exercise, we compare 90 and 91.
We know 90 is less than 91 because 90 is one unit smaller than 91. Therefore, we write:
$$90 \textless 91$$
Think of the less than symbol as an arrow that always points towards the smaller number. This helps us visually understand that the first number is smaller in value.

Greater Than Symbol

The greater than symbol (\textgreater) is used when one number is larger than another number. It points to the larger number. In our number comparison exercise, if we had the numbers switched, like comparing 91 and 90, the greater than symbol would come into play.
So in this scenario, we would write:
$$91 \textgreater 90$$
The greater than symbol works just like the less than symbol but in the opposite direction. This way, it helps us show that one number is bigger than the other.
Remember, these symbols help us quickly understand the relationship between two numbers.
