Question

the assending arrangement of (2/3),(6/7),(13/21) is​

Answer 1

(b) 13/21, 2/3, 6/7

lcm of 21, 3, 7 = 21

now, let us change each of the given fraction into an equivalent fraction having 21 as the denominator.

[(13/21) × (1/1)] = (13/21)

[(2/3) × (7/7)] = (14/21)

[(6/7) × (3/3)] = (18/21)

clearly,

(13/21) < (14/21) < (18/21)

hence,

(13/21) < (2/3) < (6/7)

hence, the given fractions in ascending order are (13/21), (2/3), (6/7)

Answer 2

Answer:

13/21 < 14/21 < 18/21

Step-by-step explanation:

Numbers = 2/3, 6/7, 13/21

first you have to convert the fractions to like,

so,

LCM of 3, 7, 21 = 21

2/3= 14/21

6/7=18/21

13/21 remains the same

So,ascending order= 13/21 < 14/21 < 18/21
