you have to add only 40 letters to the solution to get the answer
the answer is 40 liters
so my answer right because 49 - 9 litre is equal to 40 litres the 9 litres we get water ratio from the 21 is to9
ok thnx
show me the math
ok
show me the math
in 30 litres the ratio of water is to acid was 3 is to 7 so there is 9 litres of water and 21 litres of acid
then there is already 21 litres of acid is the ratio 3 is to 7 where 3 is acid and 7 is the ratio of water
so 7 x 7 is equal to 49 so 9 litres there is already what are the 49 minus 9 is equal to 40 litres
