Adding Dissimilar Fractions
Tasks :
 Finding LCD
 Adding dissimilar fractions
 Reducing fractions to lowest terms

Overview
Dissimilar Fractions – are fractions with
different denominators
3/5 and 1/4
5 and 4 , the denominators are not the
same
How do we reduce
fractions to lowest
terms ?
To find LCD, get the
least common
number in the
multiples of the
denominators.
To reduce fractions to
lowest terms, divide
the numerator and
denominator by the
GCF

Direction : Write the LCD of the following fractions on
the blank provided :
To find the LCD
get the smallest
common
multiple of the
denominators.
