To solve begin with the denominators in each problem, then the numerator as you perform
the arithmetic. Convert the fractions to decimals, denominator first, then numerator. Then
divide numerator decimal by denominator decimal. In calculation round to the thousandth
decimal (3 places to the right).

A. Change each of the following to an equivalent in decimal notation. Where appli-
cable, round to the nearest ten thousandth. This is a good exercise for you to use
your hand held calculators. Remember that the line separating the numerator
from the denominator is one of division, thus the numerator is divided by the
denominator.
