TYPES OF FRACTIONS
Equivalent Fraction.
Like Fraction.
Unlike Fractions.
Proper Fraction.
Improper Fraction.
Unit Fraction.
Mixed Number.
Proper Fraction
 Proper fraction: fraction with a smaller number
on top (numerator) than the bottom
(denominator)
Improper Fraction
 Improper Fraction: fraction with the top number
(numerator) larger than the bottom number
(denominator).
Whole Number
 Whole number: regular whole
numbers without fractions.
Talk with a
partner, think
up and write 2
more WHOLE
NUMBERS on
your worksheet
packet page.
Mixed Number
 Mixed Number: A whole number
WITH a fraction.
