the solution

Step-by-step explanation:

1 ) 6,15,12 & 30

= 6:15 , 12:30

= 2:5 , 4:10

= 2:5 , 2:5

= 2:5 = 2:5

Yes , they are in proportion.

2) 5,15,20 & 30

= 5:15 , 20:30

= 1:3 , 10:25

= 1:3 , 2:5

= 1:3 ≠ 2:5

No, they are not in proportion.

3) 20,25,28 & 40

= 20:25 , 28:40

= 4:5 , 7:10

= 4:5 ≠ 7:10

No, they are not in proportion.

☺️ Hope it helps.
