1. The problem is to round a number to the nearest tenth. 2. The rule for rounding to the nearest tenth is to look at the hundredths place (the second digit to the right of the decimal point). 3. If the hundredths digit is 5 or greater, increase the tenths digit by 1. 4. If the hundredths digit is less than 5, keep the tenths digit the same. 5. Remove all digits after the tenths place after rounding. Example: Round 3.46 to the nearest tenth. - The tenths digit is 4. - The hundredths digit is 6, which is greater than 5. - Increase the tenths digit by 1: 4 + 1 = 5. - The rounded number is 3.5. This method applies to any decimal number you want to round to the nearest tenth.
