Answer 1

Step-by-step explanation:

the answer is 192 litres of water

Answer 2

Answer:

18 Litres of water

Step-by-step explanation:

If the ratio is 8:5, then the total is 8+5 = 13. If these 13 units are equal to 78, then one unit is 78 ÷ 13 = 6. So, to make the ratio become 3:4, while keeping the amount of milk the same, we have to make the units of the milk become 8, while keeping the ratio in place. So, we times both sides by 8/3. 8/3 x 3 = 8. and 8/3 x 4 = 24/3. So, the extra water needed is 24/3 - 5, which is 9/3, which is 3. If one unit is 6, then 3 unit is 6 x 3 = 18 litres.

Hope this helps!
