ROUNDING TO THE NEAREST 10 What Is Rounding to the Nearest 10? Rounding makes numbers easier to work with if you do not need an exact number. Rounded numbers are only approximate. You can use rounded numbers to get an answer that is close but does not have to be exact. How to round to the nearest 10: 1. Read the number. 2. Identify the “tens digit” and underline it. 3. Use a number line to round to nearest ten. Remember these rules for rounding numbers to the nearest ten: • Make the numbers that end in 1 through 4 into the next lower number that ends in 0. For example 24 rounded to the nearest ten would be 20. • Numbers that end in a digit of 5 or more should be rounded up to the next ten. The number 18 rounded to the nearest ten would be 20. 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 573 rounded to the nearest 10 is 570 5345 rounded to the nearest 10 is 5,350 © Copyright NewPath Learning.
