Question

Arrange the following fractions in descending order. 3/5, 7/8, 6/9, 4/7.​

Answer 1

Answer:

LCM(5,7,9)=315

3/5=3*63/315=189/315

4/7=4*45/315=180/315

8/9=8*35/315=280/315

Ascending order:

280/315 >189/315>180/315

0.88…..>0.6>0.571428

Now 9/11=0.8181..,

Or 8/9>9/11>3/5>4/7

Answer 2

Answer:

(3/4), (5/6), (7/9), (11/12)

LCM of 4, 6, 9, 12 = 2× 2× 3× 3=36

Now, let us change each of the given fraction into an equivalent fraction having 36 as the denominator.

[(3/4) × (9/9)] = (27/36)

[(5/6) × (6/6)] = (30/36)

[(7/9) × (4/4)] = (28/360

[(11/12) × (3/3)] = (33/36)

Clearly,

(27/36) < (28/36) < (30/36) < (33/36)

Hence,

(3/4) < (7/9) < (5/6) < (11/12)

Hence, the given fractions in ascending order are (3/4), (7/9), (5/6), (11/12)
