Example Question #61 : Fractions
Find the decimal equivalent to:
To find the decimal equivalent of divide the numerator by the denominator:
Additionally, if a fraction has a base of or the ones place value of the numerator must be written in the place value that represents the name of the fraction. For example, in this problem there is a in the ones place value in the numerator and thus the is written in the hundredths place for the corresponding decimal number.
NOTE: is an improper fraction--which by definition means that the fraction represents a number larger than one whole. In this case, is equivalent to .
