#### Comparing Like Fractions

Examples:

(i) 4/9 < 7/9 or 7/9 > 4/9

(ii) 17/19 > 12/19 or 12/19 < 17/19

##### We have also learnt that three or more like fractions can be arranged in ascending or descending order by arranging their numerators in ascending or descending order.

For example, the fractions

7/10, 1/10, 4/10, 3/10 can be arranged in the ascending order as 1/10 < 3/10 < 4/10 < 7/10
Similarly, the fractions
5/17, 2/17, 6/17, 9/17 can be arranged in the descending order as 9/17 > 6/17 > 5/17 > 2/17

###### Out of two fractions with the same numerator, the one with smaller denominator is greater of the two.

Examples:

- (i) 4/7 > 4/10
- (ii) 2/3 > 2/5
- (iii) 10/13 > 10/15

###### For comparing two unlike fractions we have the following rule.

To compare two unlike fractions, we convert them into equivalent fractions by finding LCM of their denominators. Then the fractions having the larger numerator is larger than the one having the smaller numerator.

###### Alternative Method of Comparing Two Fractions

Let a/b and c/d be the two given fractions. To compare these fractions, we cross multiply, as shown:

Then we find the cross products ad and bc.

(i) If ad > bc then a/b > c/d.

(ii) If ad < bc then a/b < c/d.
(iii) If ad = bc then a/b = c/d.

### Class 6 Maths Exercise 7.5 Important Questions

### What is the meaning of unlike fraction?

Unlike fractions are fractions that have different denominators. Examples. The first fraction below has a denominator of two and the second fraction below has a denominator of three. Since the denominators are different, they are unlike fractions.

### Compare the fractions 2/5 and 3/8.

The LCM of denominators 5 and 8 is 40

Therefore, we convert 2/5 and 3/8 into like fractions each having denominator 40.

2/5 = (2 x 8)/(5 x 8) = 16/40

And 3/8 = (3 x 5)/ (8 x 5) = 15/40

Now, 16/40 and 15/40 are like fractions.

Clearly, 16 > 15

So, 16/40 > 15/40

### How do you find unlike fractions?

If the denominators are not the same, then you have to use equivalent fractions which do have a common denominator. To do this, you need to find the least common multiple (LCM) of the two denominators. To add fractions with unlike denominators, rename the fractions with a common denominator. Then add and simplify.

### How do you add and subtract unlike fractions?

When the Denominators Are Unlike or Different

When all denominators are alike, simply add or subtract the numerators and place the result over the common denominator. The resulting fraction can be simplified to lowest terms or written as a mixed number.

Compare the fractions 5/9 and 6/13.

By cross multiplying, we get:

5 × 13 = 65 and 9 × 6 = 54

Clearly, 65 > 54

Hence, 5/9 > 6/13
