B) 9:11 or 11:9. c) 23:24 or 15:16 . d) 3:10 or 15:40​

Answer 1

Answer:

c option is correct i.e 23: 24

Answer 2

Answer:

a) 4:5

b) 11:9

c) 23:24

d) 15:40

Step-by-step explanation:

a) Say, x = 5/8, y = 4/5

We may write x and y as:

x = 25/40

y = 32/40

As 32 > 25, so 32/40 > 25/40 => y > x

b) Say, x = 9/11, y = 11/9

We may write x and y as:

x = 81/99

y = 121/99

As 121 > 81, so 121/99 > 81/99 => y > x

c) Say, x = 23/24, y = 15/16

We may write x and y as:

x = 92/96

y = 90/96

As 92 > 90, so 92/96 > 90/96 => x > y

d) Say, x = 3/10, y = 15/40

We may write x and y as:

x = 12/40

y = 15/40

As 15 > 12, so 15/40 > 12/40 => y > x
