Today I'll be showing you how to round decimals, thousands and even millions! I'm going to give you an example of rounding decimals. Say you had to round 345.89 to a whole number. Notice the " 80 " in 89. Just like rounding tens if the first decimal number is 4 or less, round it down. But if it's 5 or more, round it up. Since the number is " 8 ", and that's over 5, our answer would be 346 for the 345.89 question.
Hope you learn something! Bye!
