Remind your child that decimals are another way to represent a fraction.
You can show this by reviewing the tenths, hundredths and thousandths
on the base 10 number system. Decimals are simply so many tenths or
hundredths or thousandths.
A fraction can be changed to a decimal number by dividing the numerator
by the denominator. This will usually require the addition of a decimal
point and trailing zeros.
