CONVERSION FROM UNLIKE FRACTION TO LIKE FRACTION
Like Fraction –
Fractions those have the same ‘Denominators’ are called LIKE FRACTION
5 12 24 16
Example=> --------, --------, --------, --------
45 45 45 45
Unlike Fractions –
The Fractions have different ‘Denominator’ are called UNLIKE FRACTIONS.
5 12 42 15
Example=> --------, --------, --------, --------
23 45 75 42
Unit Fractions –
Fractions those having 1 as a ‘Numerator’ are called UNIT FRACTIONS.
1 1 1 1
Example=> --------, --------, --------, --------

Q1.) Convert 4/5 , 5/6, 3/15, 3/20, 5/18 fractions into LIKE FRACTION.
4 5 3 3 5
Ans.) Fractions are => -------, -------, -------, -------,-------
5 6 15 20 18
4 5 3 3 5
=> -------, --------, --------, --------, --------
5 6 15 20 18
Step.1) Find the LCM of the ‘Denominator’ of the given fraction 5, 6, 15, 20, 18.
LCM of 5, 6, 15, 20, 18 =>
So, LCM of 5, 6, 15, 20, 18 => 5 x 3 x 2 x 2 x 3 = 180
Step.2) Divide obtained LCM which is 180 by ‘Denominator’ of the each given fraction and multiply obtained ‘Quotient’ from (LCM ÷ Denominator) with each ‘Numerator’ of the given fraction.
4 4 x 36 144
------- = ---------- ( where 180 ÷ 5 = 36 ) = ---------
5 5 x 36 180
5 5 x 30 150
------ = ---------- ( where 180 ÷ 6 = 30 ) = ----------
6 6 x 30 180
3 3 x 12 36
------ = ----------- ( where 180 ÷ 15 = 12 ) = ---------
5 15 x 12 180
3 3 x 9 27
------- = ---------- ( where 180 ÷ 20 = 9 ) = ---------
20 20 x 9 180
5 5 x 10 50
------- = ----------- ( where 180 ÷ 18 = 10 ) = --------
18 18 x 10 180
4 5 3 3 5
So, => -------, -------, -------, -------, -------
5 6 15 20 18
144 150 36 27 50
= --------, --------, --------, --------, -------- (Ans.)
180 180 180 180 180
