Reading and Writing Whole Numbers Worksheets

Reading and writing whole numbers need the understanding of place value of a certain digit in a decimal number. In other words, the position occupied by a certain digit in a number must be first determined before reading or writing the whole number. To understand this fully, consider the decimal number below.

123,456,789,012

  • Since 1 occupies HUNDRED BILLION, this means that 123 corresponds to "one hundred twenty-three billion".
  • Since 4 occupies HUNDRED MILLION, this means that 456 corresponds to "four hundred fifty-six million".
  • Since 7 occupies HUNDRED THOUSAND, this means that 789 corresponds to "seven hundred eighty-nine thousand".
  • Lastly, we just add 012 as "twelve".
Hence, 123,456,789,012 is read as "one hundred twenty-three billion, four hundred fifty-six million, seven hundred eighty-nine thousand, twelve".
