Exercise 14(B)

**1. Reduce the given fractions to their lowest terms:**

**(i) 8 / 10**

**(ii) 50 / 75**

**(iii) 18 / 81**

**(iv) 40 / 120**

**(v) 105 / 70**

**Solution:**

(i) 8 / 10

The fraction 8 / 10 can be simplified as below

8 / 10 = (8 Ã· 2) / (10 Ã· 2)

= 4 / 5

Hence 4 / 5 is the simplified form of 8 / 10

(ii) 50 / 75

The fraction 50 / 75 can be simplified as below

50 / 75 = (50 Ã· 25) / (75 Ã· 25)

= 2 / 3

Hence 2 / 3 is the simplified form of 50 / 75

(iii) 18 / 81

The fraction 18 / 81 can be simplified as below

18 / 81 = (18 Ã· 9) / (81 Ã· 9)

= 2 / 9

Hence 2 / 9 is the simplified form of 18 / 81

(iv) 40 / 120

The fraction 40 / 120 can be simplified as below

40 / 120 = (40 Ã· 40) / (120 Ã· 40)

= 1 / 3

Hence 1 / 3 is the simplified form of 40 / 120

(v) 105 / 70

The fraction 105 / 70 can be simplified as below

105 / 70 = (105 Ã· 35) / (70 Ã· 35)

= 3 / 2

Hence 3 / 2 is the simplified form of 105 / 70

**2. State, whether true or false?**

**(i) 2 / 5 = 10 / 15**

**(ii) 35 / 42 = 5 / 6**

**(iii) 5 / 4 = 4 / 5**

**(iv) 7 / 9 = **

**(v) 9 / 7 = **

**Solution:**

(i) 2 / 5 = 10 / 15

The given expression can be solved as below

2 / 5 = (10 Ã· 5) / (15 Ã· 5)

2 / 5 â‰ 2 / 3

Hence false

(ii) 35 / 42 = 5 / 6

The given expression can be solved as below

(35 Ã· 7) / (42 Ã· 7) = 5 / 6

5 / 6 = 5 / 6

Hence true

(iii) 5 / 4 = 4 / 5

The given expression can be solved as below

5 / 4 â‰ 4 / 5

Hence false

(iv) 7 / 9** = **

The given expression can be solved as below

7 / 9 = (7 Ã— 1 + 1) / 7

7 / 9 â‰ 8 / 7

Hence false

(v) 9 / 7 =

The given expression can be solved as below

9 / 7 = (7 Ã— 1 + 1) / 7

9 / 7 â‰ 8 / 7

Hence false

**3. Which fraction is greater?**

**(i) 3 / 5 or 2 / 3**

**(ii) 5 / 9 or 3 / 4**

**(iii) 11 / 14 or 26 / 35**

**Solution:**

(i) 3 / 5 or 2 / 3

The given fractions can be simplified as follows

LCM of 5, 3 is 15

Hence 3 / 5 = (3 Ã— 3) / (5 Ã— 3)

= 9 / 15 and

2 / 3 = (2 Ã— 5) / (3 Ã— 5)

= 10 / 15

We know that

10 / 15 > 9 / 15 [Numerator is greater]

Thus, 2 / 3 > 3 / 5

Hence 2 / 3 is greater fraction

(ii) 5 / 9 or 3 / 4

The given expression can be simplified as follows

First convert the given expression into like fractions

So, 5 / 9 = (5 Ã— 4) / (9 Ã— 4)

= 20 / 36 and

3 / 4 = (3 Ã— 9) / (4 Ã— 9)

= 27 / 36

We know that

27 / 36 > 20 / 36 [Numerator is greater]

Thus 3 / 4 > 5 / 9

Hence 3 / 4 is greater fraction

(iii) 11 / 14 or 26 / 35

The given expression can be simplified as follows

First convert the given expression into like fractions

So, 11 / 14 = (11 Ã— 5) / (14 Ã— 5)

= 55 / 70 and

26 / 35 = (26 Ã— 2) / (35 Ã— 2)

= 52 / 70

We know that

55 / 70 > 52 / 70 [Numerator is greater]

Thus, 11 / 14 > 26 / 35

Hence 11 / 14 is greater fraction

**4. Which fraction is smaller?**

**(i) 3 / 8 or 4 / 5**

**(ii) 8 / 15 or 4 / 7**

**(iii) 7 / 26 or 10 / 39**

**Solution:**

(i) 3 / 8 or 4 / 5

The given expression can be simplified as follows

First convert the given expression into like fractions

So, 3 / 8 = (3 Ã— 5) / (8 Ã— 5)

= 15 / 40 and

4 / 5 = (4 Ã— 8) / (5 Ã— 8)

= 32 / 40

We know that

15 / 40 < 32 / 40 [Numerator is smaller]

Thus, 3 / 8 < 4 / 5

Hence 3 / 8 is the smaller fraction

(ii) 8 / 15 or 4 / 7

The given expression can be simplified as follows

First convert the given expression into like fractions

So, 8 / 15 = (8 Ã— 7) / (15 Ã— 7)

= 56 / 105 and

4 / 7 = (4 Ã— 15) / (7 Ã— 15)

= 60 / 105

We know that

56 / 105 < 60 / 105 [Numerator is smaller]

Thus, 8 / 15 < 4 / 7

Hence 8 / 15 is the smaller fraction

(iii) 7 / 26 or 10 / 39

The given expression can be simplified as follows

First convert the given expression into like fractions

So, 7 / 26 = (7 Ã— 3) / (26 Ã— 3)

= 21 / 78 and

10 / 39 = (10 Ã— 2) / (39 Ã— 2)

= 20 / 78

We know that

20 / 78 < 21 / 78 [Numerator is smaller]

Thus, 10 / 39 < 7 / 26

Hence 10 / 39 is the smaller fraction

=48 / 60 and

7 / 15 = (7 Ã— 4) / (15 Ã— 4)

= 28 / 60 and

11 / 20 = (11 Ã— 3) / (20 Ã— 3)

= 33 / 60 and

3 / 4 = (3 Ã— 15) / (4 Ã— 15)

= 45 / 60

Hence, fractions in descending order are 4 / 5, 3 / 4, 11 / 20, 7 / 15

(iii) 5 / 7, 3 / 8, 9 / 11

The given expression can be simplified as follows

LCM of 5, 3, 9 = 3 Ã— 3 Ã— 5

= 45 / 63 and

3 / 8 = (3 Ã— 15) / (8 Ã— 15)

= 45 / 120 and

9 / 11 = (9 Ã— 5) / (11 Ã— 5)

= 45 / 55

The fraction with the smallest denominator is the biggest fraction if the numerator is same

Hence, fractions in descending order are

45 / 55, 45 / 63, 45 / 120 i.e

9 / 11, 5 / 7, 3 / 8

**6. Arrange the given fractions in ascending order of magnitude:**

3 / 8, 5 / 9, 2 / 3, 5 / 6

**7. I bought one dozen bananas and ate five of them. What fraction of the total number of bananas was left?**

**Solution:**

Given

Number of bananas bought = 1 dozen

We know there are 12 bananas in a dozen

Number of bananas eaten = 5

Number of bananas left = 12 â€“ 5

= 7

Therefore, the required fraction is 7 / 12
