Answer:
1. 10.5 liters
2. 1,500 cups of tea
3. 960 milliliters
4. 1/4 a liter
Step-by-step explanation:
1. If there are 7 days in a week, and she drinks 1.5 liters a day, we just multiply 1.5 (liters) x 7 (days) = 10.5 liters
2. There are 1000 milliliters in 1 liter. Multiply 1.5 liters by 1000 milliliters = 1,500 milliliters
3. If you multiply 800 by 0.2 (20%) you will get 160. Then add 160 + 800 = 960 milliliters
4. If you look at the fraction wall I included, you will see how there are 4/4 in 1 liter, and 2/2 in 1 liter. Half of a liter (1/2) is the same as 2/4. If you were to subtract 3/4 from 2/4, you'd get 1/4 left.
