Number Line and Comparing Numbers

1 / 6

Q: Write the inequality for this statement: "5 is less than or equal to 8."

$5 = 8$

$5 \leq 8$

$5 \geq 8$

Feedback: Not quite! The inequality "5 ? 8" correctly represents the statement "5 is less than or equal to 8."

Feedback: Well done! The inequality "5 ? 8" correctly represents the statement "5 is less than or equal to 8."

2 / 6

Q: Place 0, 10, -20, and -30 on a number line, which number is furthest to the left?

10

0

-30

-20

Feedback: Not quite! On a number line, numbers decrease as you move to the left, and the value "-30" is the smallest.

Feedback: Well done! On a number line, numbers decrease as you move to the left, and the value "-30" is the smallest.

3 / 6

Q: Write the inequality for this statement: "25 is greater than or equal to 16."

$25 \geq 16$

$25 \leq 16$

$25 = 16$

Feedback: Not quite! The inequality "25 ? 16" correctly represents the statement "25 is greater than or equal to 16."

Feedback: Well done! The inequality "25 ? 16" correctly represents the statement "25 is greater than or equal to 16."

4 / 6

Q: True or False: $12 \geq 12$.

False

True

Feedback: Not quite! The inequality "12 ? 12" means "12 is greater than or equal to 12." Since 12 is indeed equal to 12, the statement is True.

Feedback: Well done! The inequality "12 ? 12" means "12 is greater than or equal to 12." Since 12 is indeed equal to 12, the statement is True.

5 / 6

Q: Identify the greater number between 213 and 321

213

321

Feedback: Not quite! To identify the greater number, you should compare the hundreds, tens, and units place. The correct answer is 321.

Feedback: Well done! To identify the greater number, you should compare the hundreds, tens, and units place. The correct answer is 321.

6 / 6

Q: Which is greater: 3,459 or 3,498?

3,498

3,459

Feedback: Not quite! To determine which number is greater, compare the digits from left to right. Here, 3,498 is greater than 3,459.

Feedback: Well done! To determine which number is greater, compare the digits from left to right. Here, 3,498 is greater than 3,459.
