Problem: Each bottle represents the amount of water you have consumed. How much more water does each person need to drink to reach 2 liters of water?
Solution Guide:
Convert: 2 liters = 2,000 ml
+ Observe the picture to find out how much water each person has consumed.
+ The amount of water each person needs to drink more = 2,000 ml - the amount of water each person has consumed.
Answer:
Converting 2 liters = 2,000 ml
Van has consumed 1,000 ml of water. So, Van needs to drink an additional amount of water: 2,000 - 1,000 = 1,000 (ml).
Tuan has consumed 800 ml of water. So, Tuan needs to drink an additional amount of water: 2,000 - 800 = 1,200 (ml).
We fill in as follows:
Van needs to drink an additional 1,000 ml (1 liter) of water.
Tuan needs to drink an additional 1,200 ml (1 liter 200 ml) of water.
