Solve :
(a) 1 / 18 + 1 / 18
(b) 8 / 15 + 3 / 15
(c) 7 / 7 - 5 / 7
(d) 1 / 22 + 21 / 22
(e) 12 / 15 - 7 / 15
(f) 5 / 8 + 3 / 8
(g) 1 - 2 / 3 (1 = 3 / 3)
(h) 1 / 4 + 0 / 4
(i) 3 - 12 / 5

Solution:

We will use the concepts of fractions to solve this.

(a) 1 / 18 + 1 / 18

= (1 + 1) / 18

= 2 / 18

= 1 / 9

(b) 8 / 15 + 3 / 15

= (8 + 3) / 15

= 11 / 15

(c) 7 / 7 - 5 / 7

= (7 - 5) / 7

= 2 / 7

(d) 1 / 22 + 21 / 22

= (1 + 21) / 22

= 22 / 22

= 1

(e) 12 /15 - 7 / 15

= (12 - 7) / 15

= 5 / 15

= 1 / 3

(f) 5 / 8 + 3 / 8

= (5 + 3) / 8

= 8 / 8

= 1

(g) 1 - 2 / 3

= 3 / 3 - 2 / 3

= (3 - 2) / 3

= 1 / 3

(h) 1 / 4 + 0

= 1/ 4

(i) 3 - 12 / 5

= 15 / 5 - 12/ 5

= (15 - 12) / 5

= 3 / 5
