Question

Find equivalent forms of the rational numbers having a common denominator in each of the following collections of rational numbers. (i) 2/ 5, 6/ 13 (ii) 1/7, 2/ 8, 3/ 14 (iii) 5/ 12, 7/ 4, 9 /60, 11/ 3

Answer 1

Answer:

(i) 15/(-28)        

(ii) 6/(-9)        

(iii) -28/(-11)        

(iv) 19/(-7)

Step-by-step explanation:

Answer 2

Answer:

Given rational numbers = 1/7, 2/8, 3/14

LCM of the denominators = 7×8 = 56

1/7 = 1/7×8/8 = 8/56

2/8 = 2/8×7/7 = 14/56

3/14 = 3/14×4/4 = 12/56

Therefore, the required forms of given rational numbers will be -

8/56, 14/56 and 12/56.
