Unlike Fractions are fractions with different denominators. For example, \(\frac { 4 }{ 3 } \), \(\frac { 2 }{ 5 } \), \(\frac { 1 }{ 9 } \), \(\frac { 3 }{ 41 } \) are some of the examples of unlike fractions. Unequal reactions are completely different from like fractions where the denominator is the same for the like fractions.

Compared to like fractions, it is difficult to perform arithmetic operations on unlike fractions. So, we need to follow some methods to resolve unlike fractions while performing arithmetic operations and Comparing Unlike Fractions.

**Solution:**

Given fractions are \(\frac { 3 }{ 2 } \) and \(\frac { 5 }{ 6 } \)

- To compare the given fractions, first, we need to find the equivalent fractions with a common denominator. Then rearrange the fractions with the help of their numerators.
- The fractions \(\frac { 3 }{ 2 } \) and \(\frac { 5 }{ 6 } \) consists the denomiators as 2 and 6.
- The LCM or common denominator of 2 and 6 is 6.

- Now, multiply the fraction \(\frac { 3 }{ 2 } \) with 3 on top and bottom. \(\frac { 9 }{ 6 } \)
- Next, multiply the fraction \(\frac { 5 }{ 6 } \) with 1 on top and bottom. \(\frac { 5 }{ 6 } \)
- Now, both fractions are converted to like fractions.
- Compare the top numbers of the fractions to find out the large fraction. The top numbers of the fractions are 9 and 5.
- 9 is greater than 5.

Therefore, \(\frac { 3 }{ 2 } \) is greater than \(\frac { 5 }{ 6 } \).

**Question 2:
**Which is larger \(\frac { 7 }{ 4 } \) or \(\frac { 5 }{ 3 } \)?

**Solution:**

Given fractions are \(\frac { 7 }{ 4 } \) and \(\frac { 5 }{ 3 } \)

- Next, multiply the fraction \(\frac { 5 }{ 3 } \) with 4 on top and bottom. \(\frac { 20 }{ 12 } \)
- Then, multiply the number 1 with 12 on top and bottom. \(\frac { 12 }{ 12 } \).
- Also, multiply the fraction \(\frac { 2 }{ 3 } \) with 4 on top and bottom. \(\frac { 8 }{ 12 } \)
- Multiply the fraction \(\frac { 6 }{ 4 } \) with 3 on top and bottom. \(\frac { 18 }{ 12 } \)
- Now, both fractions are converted to like fractions.
- Compare the top numbers of all the fractions to find out the small and large fractions. The top numbers of the fractions are 9, 20, 12, 8, and 18.
- 20 > 18 > 12 > 9 > 8.

### Converting Unlike Fractions to Like Fractions

It is important to convert the unlike fractions to like fractions to compare them. You can generally follow two methods to compare unlike fractions to like fractions. Check out the below example to know how to convert and compare unlike fractions by converting them to like fractions.

### Comparing Fractions with Unlike Denominators Examples

**Example 1.
**Compare \(\frac { 7 }{ 6 } \) and \(\frac { 5 }{ 9 } \).

**Solution:** Method 1: Convert the given unlike fractions into like fractions.

To convert the unlike fractions into like fractions, find the LCM of the denominators of the given fractions.

LCM of denominators 6 and 9 is 18.

Now, multiply the fraction \(\frac { 7 }{ 6 } \) with 3 on top and bottom. \(\frac { 21 }{ 18 } \). Next, multiply the fraction \(\frac { 5 }{ 9 } \) with 2 on top and bottom. \(\frac { 10 }{ 18 } \).

Now, both fractions are converted to like fractions.

As both the denominators are equal now, you can compare the numerators to find the largest and smallest number.

\(\frac { 21 }{ 18 } \) > \(\frac { 10 }{ 18 } \).

So, \(\frac { 7 }{ 6 } \) > \(\frac { 5 }{ 9 } \).

Method 2: We can also use cross multiplication to convert the unlike fractions to like fractions.

So, firstly take the given fractions. The given fractions are \(\frac { 7 }{ 6 } \) and \(\frac { 5 }{ 9 } \).

Now, cross multiply the given fractions.

7 × 9 = 63; 6 × 5 = 30.

63 > 30.

Therefore, \(\frac { 7 }{ 6 } \) is greater than \(\frac { 5 }{ 9 } \).

### Word Problems on Comparing Unlike Fractions

**Question 1. **

Sam ate \(\frac { 3 }{ 18 } \) part of the chocolate and Sophia ate \(\frac { 5 }{ 9 } \) part of the chocolate. Who ate the greater part of the chocolate? What fraction of chocolate was finished by the two girls?

**Solution:**

Given that Sam ate \(\frac { 3 }{ 18 } \) part of the chocolate and Sophia ate \(\frac { 5 }{ 9 } \) part of the chocolate.

Firstly, take the fractions and convert them into like fractions.

LCM of 9 and 18 is 18.

So, \(\frac { 3 }{ 18 } \) and \(\frac { 10 }{ 18 } \) are the like fractions now.

Compare the two fractions \(\frac { 3 }{ 18 } \) and \(\frac { 10 }{ 18 } \).

As 10 is greater than 3, \(\frac { 5 }{ 9 } \) is greater than \(\frac { 3 }{ 18 } \). Sophia ate a greater part of the chocolate.

Now, add two fractions to find the chocolate finished by the two girls.

\(\frac { 3 }{ 18 } \) + \(\frac { 5 }{ 9 } \) = \(\frac { 3 + 10 }{ 18 } \) = \(\frac { 13 }{ 18 } \).

\(\frac { 13 }{ 18 } \) fraction of chocolate was finished by the two girls.

**Question 2. **

Ram traveled \(\frac { 10 }{ 6 } \) km of distance in a car and alex traveled \(\frac { 6 }{ 4 } \) km of distance in a car. Who covered the greater distance?

**Solution:**

Given that Ram traveled \(\frac { 10 }{ 6 } \) km of distance in a car and alex traveled \(\frac { 6 }{ 4 } \) km of distance in a car.

Firstly, take the fractions and convert them into like fractions.

LCM of 6 and 4 is 12.

So, \(\frac { 20 }{ 12 } \) and \(\frac { 18 }{ 12 } \) are the like fractions now.

Compare the two fractions \(\frac { 20 }{ 12 } \) and \(\frac { 18 }{ 12 } \).

As 20 is greater than 18, \(\frac { 10 }{ 6 } \) is greater than \(\frac { 6 }{ 4 } \).

Therefore, Ram traveled more distance compared to Alex.

**Question 3.**

Yash walked for \(\frac { 62 }{ 4 } \) km and William walked for \(\frac { 27 }{ 2 } \) km during the weekend. Who cycled more and by how much?

**Solution:**

Given that Yash walked for \(\frac { 62 }{ 4 } \) km and William walked for \(\frac { 27 }{ 2 } \) km during the weekend.

Firstly, take the fractions and convert them into like fractions.

LCM of 2 and 4 is 4.

So, \(\frac { 62 }{ 4 } \) and \(\frac { 54 }{ 4 } \) are the like fractions now.

Compare the two fractions \(\frac { 62 }{ 4 } \) and \(\frac { 54 }{ 4 } \).

As 62 is greater than 54, \(\frac { 62 }{ 4 } \) is greater than \(\frac { 27 }{ 2 } \).

\(\frac { 62 }{ 4 } \) – \(\frac { 27 }{ 2 } \) = 2

Therefore, Yash walked more compared to William. Yash walked 2km more than William.
