Two numbers that compose a

fraction are called the:

Numerator

Denominator

THE DENOMINATOR

tells into how manyparts the whole is

divided.THE NUMERATOR

indicates the

represented number

of pieces of the whole.

The 3 is the numerator ;

the 5 is the denominator.

There are five parts thatmake up the whole.

Only those part are being

c.Mixed Numbers

20/53

PROPER FRACTION

the numerator is smaller than the

denominatorindicating a part of awhole.

the value of proper fraction is < 1.

8/14/2019 F r a Ction

21/53

IMPROPER FRACTION

the numerator is larger than the

denominatorindicating a whole ormixed number.

The value of an improper fractionis 1 or more.

MIXED NUMBERS

a whole number and a properfraction indicating whole

number(s) plus a part of a

whole.

The value of a mixed number is

> 1 : it is the sum of the wholenumber plus the fraction.

To Change an Improper Fraction

into mixed number or a whole

number:1. Divide the denominator into the

numerator2.If there is a remainder, change it

into a fraction by writing it as the

top number over the bottomnumber of the improper fraction.

Write it next to the whole number.

To change a mixed number into

an improper fraction :

1. Multiply the whole number by

the bottom number2.Add the top number to the

product of step 1.

3.Write the total as the topnumber of a fraction over the

original bottom number.
