🛎️ Understanding the Number Line
- Numbers get bigger as you move right on the number line.
- Numbers are spaced at equal intervals along the line.
🛎️ Using Inequality Symbols
- The symbol > means greater than and < means less than.
- The symbols ≥ and ≤ include equal to as well.
🛎️ Comparing Positive Numbers
- A number with more digits is usually greater if both are positive.
- If the digits are equal, compare from left to right. The number with the first bigger digit is larger.
Practice Questions
Test your understanding
Write the inequality for this statement: "5 is less than or equal to 8."
Correct! 🎉 +10 pointsNot quite right
The inequality "" correctly represents the statement "5 is less than or equal to 8."
Place 0, 10, -20, and -30 on a number line, which number is furthest to the left?
Correct! 🎉 +10 pointsNot quite right
On a number line, numbers decrease as you move to the left, and the value "-30" is the smallest.
Write the inequality for this statement: "25 is greater than or equal to 16."
Correct! 🎉 +20 pointsNot quite right
The inequality "" correctly represents the statement "25 is greater than or equal to 16."
True or False: .
Correct! 🎉 +20 pointsNot quite right
The inequality "" means "12 is greater than or equal to 12." Since 12 is equal to 12, the statement is True.
Identify the greater number between 213 and 321.
Correct! 🎉 +20 pointsNot quite right
When comparing numbers with the same number of digits, compare from left to right. The hundreds digit of 321 is 3, which is greater than 2 in 213, so 321 is the larger number.
Which is greater: 3459 or 3498?
Correct! 🎉 +30 pointsNot quite right
When comparing numbers, check digits from left to right. Both start with 34, but in the tens place 9 > 5, so 3498 is greater than 3459.
