📚 Topic Summary
Rounding decimals simplifies numbers to a desired place value. When rounding to the nearest whole number, look at the tenths place. If it's 5 or greater, round up; otherwise, round down. For rounding to the nearest tenth, examine the hundredths place, and for rounding to the nearest hundredth, check the thousandths place. Remember, 5 or more rounds up, less than 5 rounds down. Understanding place value is crucial for mastering rounding!
