The ascending arrangement of 2/3, 6/7, 13/21 is:
a. 6/7, 2/3,13/21
b. 13/21, 2/3, 6/7
c. 6/7,13/21, 2/3
d. 2/3, 6/7,13/21

Solution:

We have given data as 2/3, 6/7, 13/21. To compare the fractions, we take the LCM of denominators.

LCD(3, 7, 21) = 21

2/3 = (2 × 7)/(3 × 7) = 14/21

6/7 = (6 × 3)/(7 × 3) = 18/21

13/21 = (13 × 1)/(21 × 1) = 13/21

Since, 13 < 14 < 18

Therefore, the ascending arrangement is 13/21, 2/3, 6/7.
