Answer 1

In winter, mix 250 ml of screenwash with 750 ml of water.

Step-by-step explanation:

In winter, you should mix 1 part screenwash with 3 parts water. This means that for every 1 ml of screenwash, you should mix it with 3 ml of water.

Since you have 250 ml of screenwash, you need to calculate 3 times that amount for the water.
