Let's go through each statement one by one and determine whether it is true or false:
1. When rounding, you usually round to the closest number.
- This statement is True. When rounding a number, the standard approach is to round to the nearest value.
2. When a number is halfway between the two possible numbers, round down to the smaller number.
- This statement is False. The standard rounding procedure, often called round half up, dictates that you round up when the number is exactly halfway between two numbers.
3. When a number is halfway between the two possible numbers, round up to the greater number.
- This statement is True. When a number is exactly halfway between two possible rounded values, we round up to the higher number.
4. If you are rounding 897 to the nearest hundred, 890 and 900 are the two possible numbers you choose between based on whether you are rounding up or down.
- This statement is True. When rounding 897 to the nearest hundred, the two candidates for rounding are 800 and 900, confirming that they round up to 900.
So, the correct matches are:
- TRUE
- When rounding, you usually round to the closest number.
- When a number is halfway between the two possible numbers, round up to the greater number.
- If you are rounding 897 to the nearest hundred, 890 and 900 are the two possible numbers you choose between based on whether you are rounding up or down.
- FALSE
- When a number is halfway between the two possible numbers, round down to the smaller number.
