Answer 2

Answer:

see first we want to put them on ratio.

w:a w:a w:a

2:3 7:3 11:9

so we want to find the ratio of water and alcohol.

so we can see alcohol is 3:3:9 so we want to make it 9 of the other two ratio so multiply by ×3 both side. The new ratio we get

6:9 7:9 11:9

Now by adding it

6+9:7+11

15:18

By cancelling.

5:6

5:3
