Ordering 0.640.64 and 0.60.6

Determine whether 0.640.64 is greater than or less than 0.60.6 by applying the decimal ordering procedure:

  1. Align decimal points: Write 0.640.64 above 0.60.6 with the decimal points lined up vertically.
  2. Equalize decimal places: The number 0.640.64 has two decimal places while 0.60.6 has only one. Append a zero to 0.60.6 to obtain the equivalent decimal 0.600.60, so that both numbers are expressed in hundredths.
  3. Compare as whole numbers: Treating the digits after the decimal as whole numbers gives 6464 and 6060. Since 64>6064 > 60, it follows that 6464 hundredths is greater than 6060 hundredths.
  4. State the result: Therefore, 0.64>0.60.64 > 0.6.
