What is the value with decimals?
               If you had $1.00, and
               had to divide it evenly
               between the 4 pieces,
               how much would go in
               each piece?
$1.00 divided into 4 pieces
$1.00 divided into 4 pieces

Converting a Decimal to a Fraction
When given a decimal and you need the fraction
conversion
1. Numerator
  – The digits to the right of the decimal point
2. Denominator
  – The place value of the last digit
3. Simplify into simplest form if necessary
