1) 2/5, 3/5, 8/5, 11/5 are like-fractions as the denominator 5 is same in all fractions.

2) 11/15, 23/15, 112/15 are like-fractions as the denominator 15 is same in all the fractions.

3) 7,6,5 are like-fractions as there is no denominator so consider 1 as a denominator so it will be 7/1,6/1 and 5/1.

The fractions with different denominators are called Unlike fractions.

1) 3/7, 8/5, 12/11 are unlike fractions as in each fraction denominators are different.

2) 4/11, 1/2, 3/4, 6/13 are unlike fractions as in each fraction denominators are different.

1) Convert 4/5 and 3/2 into like-fractions.

As both 4/5 and 3/2 are unlike fractions,

so the LCM of 5 and 2 = 10

4/5 = (4x2)/(5x2) = 8/10

3/2 = (3x5)/(2x5)= 15/10

Now 8/10 and 15/10 are like-fractions.

2) Convert 3/8, 5/6, 7/12 into like-fractions.

Find the LCM of the denominators 8,6 and 12.

LCM = 24

Now convert above fraction into

3/8 = (3 x 3)/(8 x 3)= 9/24

5/6 = (5 x 4)/(6 x 4)= 20/24

7/12 = (7 x 2)/(12 x 2)= 14/24

So, 9/24, 20/24, and 14/24 are like-fractions representing 3/8, 5/6 and 7/12.
