Question

The other day, we made green water by mixing 5 ml of blue water with 15 ml of yellow water. We want to make a very small batch of the same shade of green water. We want to know how much yellow water to mix with only 1 ml of blue water.

Answer 1

yellow 3ml

Explanation:

they are making the batch 5 times less than before. so divide each quantity by 5.

5/5 = 1 blue

15/5 = 3 yellow
