Exercise 14(C)
1. Add the following fractions:
(i) 
and 3 / 8
(ii) 2 / 5, 
and 7 / 10
(iii) 
, 
and 
(iv) 
, 
, and 
(v) 
, 11 / 18 and 
Solution:
(i)
and 3 / 8
The given fractions can be added as follows
7 / 4 + 3 / 8 = (7 × 2) / (4 × 2) + 3 / 8
= 14 / 8 + 3 / 8
= 17 / 8
=
Hence,
is the addition of given fractions
(ii) 2 / 5,
and 7 / 10
The given fractions can be added as follows
2 / 5 + 33 / 15 + 7 / 10 = (2 × 6) / (5 × 6) + (33 × 2) / (15 × 2) + (7 × 3) / (10 × 3)
= 12 / 30 + 66 / 30 + 21 / 30
= 99 / 30
= 33 / 10
=
Hence,
is the addition of given fractions
(iii)
,
and
The given fractions can be added as follows
15 / 8 + 3 / 2 + 7 / 4 = (15 × 1) / (8 × 1) + (3 × 4) / (2 × 4) + (7 × 2) / (4 × 2)
= 15 / 8 + 12 / 8 + 14 / 8
= 41 / 8
=
Hence,
is the addition of the given fractions
(iv)
,
and
The given fractions can be added as follows
15 / 4 + 13 / 6 + 13 / 8 = (15 × 6) / (4 × 6) + (13 × 4) / (6 × 4) + (13 × 3) / (8 × 3)
= 90 / 24 + 52 / 24 + 39 / 24
= 181 / 24
=
Hence,
is the addition of given fractions
(v)
, 11 / 18 and
The given fractions can be added as follows
26 / 9 + 11 / 18 + 23 / 6 = (26 × 2) / (9 × 2) + 11 / 18 + (23 × 3) / (6 × 3)
= 52 / 18 + 11 / 18 + 69 / 18
= 132 / 18
= 22 / 3
=
Hence,
is the addition of given fractions
2. Simplify:
(i) 
– 13 / 16
(ii) 
– 
(iii) 
+ 3 / 14 – 13 / 21
(iv) 
– 1 / 6 – 
(v) 6 + 3 / 10 – 
Solution:
(i)
– 13 / 16
The given expression can be simplified as below
23 / 12 – 13 / 16 = (23 × 4) / (12 × 4) – (13 × 3) / (16 × 3)
= (92 – 39) / 48
= 53 / 48
=
Hence, simplified form of the given expression is
(ii)
–
The given expression can be simplified as below
11 / 4 – 11 / 6 = (11 × 6) / (4 × 6) – (11 × 4) / (6 × 4)
= (66 – 44) / 24
= 22 / 24
= 11 / 12
Hence, simplified form of the given expression is 11 / 12
(iii)
+ 3 / 14 – 13 / 21
The given expression can be simplified as below
19 / 7 + 3 / 14 – 13 / 21 = (19 × 6) / (7 × 6) + (3 × 3) / (14 × 3) – (13 × 2) / (21 × 2)
= 114 / 42 + 9 / 42 – 26 / 42
= (114 + 9 – 26) / 42
= 97 / 42
=
Hence, simplified form of the given expression is
(iv)
– 1 / 6 –
The given expression can be simplified as below
23 / 6 – 1 / 6 – 13 / 12 = (23 × 2) / (6 × 2) – (1 × 2) / (6 × 2) – 13 / 12
= 46 / 12 – 2 / 12 – 13 / 12
= (46 – 2 – 13) / 12
= 31 / 12
=
Hence, simplified form of the given expression is
(v) 6 + 3 / 10 –
The given expression can be simplified as below
6 / 1 + 3 / 10 – 23 / 15 = (6 × 30) / (1 × 30) + (3 × 3) / (10 × 3) – (23 × 2) / (15 × 2)
= 180 / 30 + 9 / 30 – 46 / 30
= (180 + 9 – 46) / 30
= 143 / 30
=
Hence, simplified form of the given expression is
