To review the statement that reducing
a
fraction does NOT change its value:
16/32 has the same value as 8/16 or as 4/8
or
16/32 = 8/16 = 4/8 = 1/2
Remember to reduce
all
fractions
to
their
LOWEST terms.

1/4 + 1/2 = ****
In order to add fractions, you must find a
number into which the denominators will
divide. This is called a COMMON DENOMINATOR.
The number into which the denominators of all
fractions to be added will divide is the
_______________ _______________.

1/4 + 1/2 = ****
To find the common denominator, we try the
common denominator
inspection method first.
By inspecting the
problem, we notice that there are many numbers
(such as 4, 8, 16, 4000, etc.) into which both
denominators will divide.
However, we want
the smallest of these numbers, to simplify
working the problem. This number, called the
lowest common denominator or l.c.d., is
_______________.
