Content and Presentation
Understanding Capacity, Multiplication, and Division in Litres
- Basic Unit of Measurement: Litres 🥤
- Litres (L) are used to measure the capacity or volume of liquids.
- Multiplication with Litres ✖️
- Multiplication helps us find the total capacity when we have multiple containers with the same volume.
- Example: If a bottle holds 2 litres and there are 3 bottles, the total capacity is 2 litres × 3 bottles = 6 litres.
- Division with Litres ➗
- Division helps us distribute a given quantity of liquid equally among containers.
- Example: If we have 6 litres of juice and want to pour it into 3 bottles, each bottle will get 6 litres ÷ 3 bottles = 2 litres.
- Word Problems with Litres 📝
- We can solve word problems involving multiplication and division of litres.
- Example: If each jug holds 4 litres of water and there are 5 jugs, how much water is there in total?
- Real-Life Applications 🏡
- Understanding capacity helps us in real-life situations like cooking, filling water bottles, or distributing drinks at a party.
Examples and Practice
- Example 1: Multiplication with Litres
- Problem: If there are 4 water bottles with 3 litres each, how much water is there in total?
- Solution: 3 litres × 4 bottles = 12 litres.
- Example 2: Division with Litres
- Problem: If we have 12 litres of milk and want to pour it into 6 cups, how much milk is in each cup?
- Solution: 12 litres ÷ 6 cups = 2 litres per cup.
- Example 3: Word Problem
- Problem: If there are 5 jugs, each holding 2 litres of juice, how much juice is there in total?
- Solution: 2 litres × 5 jugs = 10 litres.
Conclusion
Understanding how to multiply and divide litres helps us manage liquids better in everyday life! 🥤✨
