​

Answer 1

Answer:

i) 15:22

(ii) 5:9

(iii) 4:11

(iv) 7:21

Step-by-step explanation:

(i) 10:7 & 15:22

by cross multiplying we get,

10:7=220

15:22=105

Therefore, 15:22 < 10:7.

(ii) 5:9 & 23:14

by cross multiplying we get,

5:9=70

23:14=207

Therefore, 5:9 < 23:14.

(iii) 9:16 & 4:11

by cross multiplying we get,

9:16=99

4:11=64

Therefore, 4:11 < 9:16

iv) 7:21 or 2:5

by cross multiplying we get,

7:21=35

2:5=42

Therefore, 7:21 < 2:5
