Question

communicate and justify danny said 12.309 rounded to the nearest tenth is 12.4. is danny correct? explain.

Explanation:

Step1: Recall rounding rules

To round a number to the nearest tenth, we look at the hundredth place. If the digit in the hundredth place is 5 or greater, we round up the tenths place; if it's less than 5, we leave the tenths place as is.

Step2: Analyze 12.309

For 12.309, the tenths place is 3, the hundredths place is 0, and the thousandths place is 9. Since we are rounding to the nearest tenth, we only care about the hundredth place (0) for the rounding decision.

Step3: Apply the rule

Since 0 (in the hundredth place) is less than 5, we do not round up the tenths place. So 12.309 rounded to the nearest tenth is 12.3, not 12.4.

Answer:

Danny is not correct. When rounding 12.309 to the nearest tenth, we check the hundredth place (0). Since 0 < 5, we keep the tenths place digit (3) as is, so 12.309 rounded to the nearest tenth is 12.3, not 12.4.
