Answer 1

a) 7:9 b) 7:3 by cross multiplication

Answer 2

Answer:

7:19 < 11:23

9:11 < 7:3

Step-by-step explanation:

i )

7:19 = 7/19

11:23 = 11/23

LCM of 19 and 3 = 19×23 = 427

7/19 = (7×23)/(19×23)

= 161/437

11/23 = (11×19)/(23×19)

= 209/437

161/437 < 209/427

7:19 < 11:23

Therefore, 7:19 < 11:23

ii )

9:11 = 9/11

7:3 = 7/3

9/11 < 7/3

( Because Improper Fraction is always greater than a Proper Fraction )

Therefore, 9:11 < 7:3
