1. The problem asks to round the number 2.7 to the nearest tenth. 2. The rule for rounding to the nearest tenth is to look at the hundredths place (the second digit after the decimal point). 3. If the hundredths digit is 5 or greater, round the tenths digit up by 1. 4. If the hundredths digit is less than 5, keep the tenths digit the same. 5. In the number 2.7, the tenths digit is 7 and there is no hundredths digit explicitly shown, which means it is 0. 6. Since the hundredths digit is 0 (less than 5), we keep the tenths digit 7 as it is. 7. Therefore, 2.7 rounded to the nearest tenth is 2.7.
