Answer:
Step-by-step explanation:
Table 1
3:5 , 6 : 10 , 9 :15 , 12 : 20
Table 2
7 : 10 , 14 : 20 , 21 : 30 , 28 : 40
All table 1 Ratios are equal
All table 2 Ratios are equal
3 : 5
= 6 : 10
6 < 7
=> 6 : 10 < 7 : 10
=> 3 : 5 < 7 : 10
=> The ratio 3:5 is less than the ratio 7:10
All table 1 Ratios are equal
All table 2 Ratios are equal
=> All table 1 Ratios are less than the ratios in Table 2
The ratio 14:20 is greater than the ratio 9:15.
