Strategies
Knowledge of the naming conventions for fractions as well as geometric representations of tenths and hundredths are encouraged to ensure success on this exercise.
 * 1) To transfer a decimal number into tenths, multiply by ten. To transfer tenths into decimals, divide by ten.
 * 2) To transfer a decimal number into hundredths, multiply by 100. To transfer hundredths into decimals, divide by 100.

Real-life Applications

 * 1) The tenths and hundredths are important in the naming conventions for fractions, as well as serving as a basic intermediary between decimals and fractions.
