Question

Look at the digit to the right of the digit to which you are rounding to tell whether to round up or leave it the same.

A. True
B. False

Answer 1

It is true that when rounding numbers, the digit to the right of the one being rounded influences the rounding decision; less than 5 means round down, 5 or greater means round up.

Step-by-step explanation:

The claim that you should look at the digit to the right of the one you are rounding to decide whether to round up or leave it the same is true. When rounding numbers, if the digit to the right (the one you are dropping) is less than 5, you round down and keep the current digit the same. If this digit is greater than or equal to 5, you round up by increasing the retained digit by 1.

For example:

• 0.028675 rounds 'up' to 0.0287 (since the dropped digit, 7, is greater than 5).
• 18.3384 rounds 'down' to 18.3 (since the dropped digit, 3, is less than 5).
• 6.8752 rounds 'up' to 6.88 (there's a 5 followed by a nonzero digit).
• 92.85 rounds 'down' to 92.8 (the dropped digit is 5, and the retained digit is even, resulting in an even value).
