Example Problems and Solutions:
####
1. Rounding Numbers
#####
a) Rounding 2-digit numbers to the nearest 10:
-
Rule: Look at the ones place. If it is 5 or greater, round up; if it is less than 5, round down.
-
Example Problem: Round 39 to the nearest 10.
-
Solution: The ones digit is 9 (which is ≥ 5), so round up.
-
Answer: 40
-
Another Example: Round 46 to the nearest 10.
-
Solution: The ones digit is 6 (which is ≥ 5), so round up.
-
Answer: 50
#####
b) Rounding 3-digit numbers to the nearest 10:
-
Rule: Look at the ones place. If it is 5 or greater, round up; if it is less than 5, round down.
-
Example Problem: Round 131 to the nearest 10.
-
Solution: The ones digit is 1 (which is < 5), so round down.
-
Answer: 130
-
Another Example: Round 812 to the nearest 10.
-
Solution: The ones digit is 2 (which is < 5), so round down.
-
Answer: 810
#####
c) Rounding 3-digit numbers to the nearest 100:
-
Rule: Look at the tens place. If it is 5 or greater, round up; if it is less than 5, round down.
-
Example Problem: Round 462 to the nearest 100.
-
Solution: The tens digit is 6 (which is ≥ 5), so round up.
-
Answer: 500
-
Another Example: Round 375 to the nearest 100.
-
Solution: The tens digit is 7 (which is ≥ 5), so round up.
-
Answer: 400
####
2. Comparing Numbers
#####
Example Problem: Compare 61 and 36 using `<`, `>`, or `=`.
-
Solution: 61 is greater than 36.
-
Answer: 61 > 36
#####
Another Example: Compare 42 and 22 using `<`, `>`, or `=`.
-
Solution: 42 is greater than 22.
-
Answer: 42 > 22
#####
Ordering Numbers:
-
Example Problem: Order the numbers 60, 85, 37, 70 from smallest to largest.
-
Solution: Arrange the numbers in ascending order: 37, 60, 70, 85.
-
Answer: 37, 60, 70, 85

General Steps to Solve These Problems:
1.
For Rounding:
- Identify the place value you are rounding to (nearest 10 or 100).
- Look at the digit to the right of the rounding place.
- Apply the rounding rule (round up if ≥ 5, round down if < 5).
2.
For Comparing:
- Compare the digits from left to right.
- Use the symbols `<`, `>`, or `=` based on which number is larger or smaller.
3.
For Ordering:
- Arrange the numbers in either ascending (smallest to largest) or descending (largest to smallest) order.
