Question

7 by 12, 5 by 36, 9 by 18, 13 by 24 arrange in descending order fractions​

Answer 1

Answer:

7 by 12 , 5 by 36 , 9 by 18 , 13 by 24

at first we need to find the Lcm of the denominators_

3        12  , 36 , 18 , 24

2        4,     12,    6,   8

2        2,     6,    3  , 4          

3         1,     3,    3,   2

3         1,     1,      1,   2

2         1,      1,     1 ,  1

therefore 3*2*2*3*3*2=216

7 by 12 = 126 by 216

5 by 36 =  30 by 216

9 by 18  = 108 by 216

13 by 24 = 117 by 216

so , 126 by 126 (7 by 12) ≥ 117 by 216 (13 by 24) ≥ 108 by 216 (9 by 18) ≥ 30 by 216 (5 by 36)
