How many water do you need to mix with 200ml of shampoo? How many water should you mix with 500ml of shampoo? If the correct amount of water is mixed with 400ml of shampoo will the mixture fit in a 2500ml container?

200 mL shampoo - 1050 ml water

500 mL shampoo - 2625 mL water

Step-by-step explanation:

1) 400 ml shampoo, should be mixed 2500 - 400 = 2100 mL of water.

2) 400 mL shampoo - 2100 mL water

200 mL shampoo - x mL water

x = 200*2100/400 = 1050 mL water

3) 400 mL shampoo - 2100 mL water

500 mL shampoo - x mL water

x = 500*2100/400 = 2625 mL water
