Like Fractions

All fractions with the

__same denominators__(i.e. number written below the horizontal line) are called**like fractions**.Example: 2/14, 3/14, 4/14, 5/14 are like fractions as all fraction have same bottom number i.e. denominator.

Unlike Fractions

All fractions with the

__different denominators__(i.e. number written below the horizontal line) are called**unlike fractions.**Example: 2/3, 5/14, 7/8, 9/13 are unlike fractions as all fraction have different bottom number i.e. denominator.

Conversion of Unlike Fractions to Like Fractions

*Step1*. Find the LCM of the denominators of the given fractions.*Step2.*Find the quotient by dividing the LCM by denominator of the given fractions.*Step3.*Multiply the numerator by corresponding quotient.Example: Convert 2/9 and 5/6 to like fractions.

**Step 1:**LCM of 9 and 6 = 2 x 3 x 3 = 182

9,6

3

9,3

3

3,1

1,1

Now, we have to adjust the numerators to the LCM =18

**Step 2:**__Convert 2/9__Numerator to be multiplied by (18/9 = 2)

Changed numerator = 2 x 2 = 4

2/9 (old fraction) = 4/18 (new fraction)

__Convert 5/6__Numerator to be multiplied by (18/6 = 3)

Changed numerator = 5 x 3 = 15

5/6 (old fraction) = 15/18 (new fraction)

**Therefore; 4/18 and 15/18 are the required like fractions.**Comparing Like Fractions

In like fractions, the fraction with the greater numerator is greater.

Example: Compare 4/5 and 3/5

Here numerators are 4 and 3.

And 4 > 3

Therefore, 4/5 > 3/5

Comparing Unlike Fractions

**Step 1:**Find the denominators of the fractions and find their LCM.**Step 2:**Convert each given fraction to equivalent fraction with denominator equal to the LCM.**Step 3:**Now compare the numerators of the equivalent fractions whose denominators are same.Example: Compare 3/8 and 4/6.

**Step 1:**LCM of 8 and 6 = 2 x 2 x 2 x 3 = 242

8,6

Now, we have to adjust the numerators to the LCM =24

**Step 2:**__Convert 3/8__Numerator to be multiplied by (24/8 = 3)

Changed numerator = 3 x 3 = 9

3/8 (old fraction) = 9/24 (new fraction)

__Convert 4/6__Numerator to be multiplied by (24/6 = 4)

Changed numerator = 4 x 4 = 16

4/6 (old fraction) = 16/24 (new fraction)

Therefore; 9/24 and 16/24 are the required like fractions.

Now compare numerators of the two like fractions

16 > 9

Therefore; 16/24 > 9/24

i.e. 4/6 > 3/8
