• D. 12.8

Answer 1

The correct option is D 12.8

Steps to estimate 12.84 to nearest tenths

Step 1: Locate the number mentioned in nearest place value i.e locate the tenths column, the number is 8

Step 2: Look at the digit to the right of the digit you want to estimate i.e., 4 (in hundredths place)

Step 3: Follow the rule: If you see a digit nearest to the tenths greater than 5, round up, and if it's less than 5, round down.
4 (in hundredths place) nearest to tenths is less than 5, so leave a digit in the tenths place as it is.

Hence, 12.84 estimated to the nearest tenths is 12.8
