" *Equal Value* fractions are called *equivalent fractions* "
example -
4 5 6
------ , ------ , ------- etc
8 10 12
question - Find fractions equivalent to 18/60 ?
*solution ,...*
18 ÷ 2 9
-------------- = ------
60 ÷ 2 30
18 ÷ 3 6
--------------- = ---------
60 ÷ 3 20
18 × 2 36
------------- = -------
60 × 2 120
So.... *18/60 , 9/30 , 6/20 , 36/120 are equivalent fractions*
ЁЯЕ┐.... *By multiple or division with same number to Numerator & Denominator we get equivalent fractions*

ЁЯЕ┐ *Like fractions*
~~~~~~~~~~~
" *fractions with equal denominators are called like fractions* "
example .....
4 6 7
----- , ----- , ------
8 8 8
Here denominator 8 is same hence those fractions called *like fractions*
ЁЯЕ┐ *Unlike fractions*
~~~~~~~~~~~~
" *fractions with different denominator are called unlike fractions* "
example ...........
4 9 14
----- , ------ , --------
6 7 4
Here denominator is different hence its called *unlike fractions*
ЁЯЕ┐ *Converting Unlike fractions to like fractions*
example .......
*convert 9/4 & 7/5 to like fractions*
solution
First we find common multiple for 4 & 9 ......
*multiple of 4 - 4, 8 , 12 , 16 , 20 , 24..*
*multiple of 5 - 5 , 10 , 15 , 20 , 25....*
here number 20 is multiple of both 4 & 5 .....
so we *make denominator 20 both fractions*
9 × 5 45
------------- = ---------
4 × 5 20
7 × 4 28
------------ = -----------
5 × 4 20
*Thus 45/20 & 28/20 are like fractions*

----- , -----
9 9
when denominator are same *the fractions with greater numerators is the greater fractions*
here 7 is greater than 4.....
*hence 7/9 is greater than 4/9*
ЁЯЕ┐ *when numerators same*
8 8
----- , ------
3 5
when numerators same *the fractions with smaller denominator is greater fractions*
Here 3 is smaller than 5 ....
*hence 8/3 is greater than 8/5*

take multiple of.....
5 × 9 = 45
7 × 8 = 56
here ...... *45 < 56*
hence .... *5/8 < 7/9*
