1. The problem is to understand and practice rounding off numbers to a specified place value. 2. Rounding off means adjusting a number to make it simpler but still close to the original value. 3. To round a number, look at the digit immediately to the right of the place value you want to round to. 4. If that digit is 5 or greater, increase the rounding digit by 1. 5. If that digit is less than 5, keep the rounding digit the same. 6. Replace all digits to the right of the rounding digit with zeros (if rounding whole numbers) or remove them (if rounding decimals). Example questions: 1. Round 346 to the nearest ten. 2. Round 7.856 to the nearest hundredth. 3. Round 12345 to the nearest thousand. 4. Round 0.049 to the nearest tenth. 5. Round 999.99 to the nearest whole number. These questions help practice rounding off to different place values.
