Answer 1

Answer:

alcohol and water first glass 2/3 and in second is 3/2

if it is multiply by 15 (asLCM )

it will be

first ...

alcohol (10/15)and water(5/15)

and second

alcohol (9/15) and water(6/15)

so total alcohol in third glass is (10/15+9/15)= 19/15

and total water is = (5/15)+(6/15)= 9/25

proportion of alcohol and water in third glass is =

19:9
