Examples on Multiples of 7
Example 1: Sharing Slices of Pizza
You have 21 slices of pizza and want to share them equally among 3 friends. Each friend gets: 21÷3 = 7 Since 21 can be divided evenly by 7, 21 is a multiple of 7.
Example 2: Counting Weeks
If you count in weeks, every 7 days is a new week. For instance, after 5 weeks, you have: 7×5 = 35 So, 35 days is a multiple of 7, representing 5 weeks.
Example 3: Packaging Items
You have 63 apples to pack into boxes, with each box holding 7 apples. The number of boxes needed will be: 63÷7 = 9 Since 63 can be divided evenly by 7, 63 is a multiple of 7, requiring 9 boxes.
Practical Examples of Multiples of 7
Example 1: Weekly Planning
If you plan a weekly schedule, every 7 days marks a new week. For instance, if today is Monday, the next Monday will be in: 7×1 = 7 days And two weeks later will be: 7×2 = 14 days This helps in organizing tasks and events on a weekly basis.
Example 2: Classroom Arrangement
A teacher has 28 students and wants to arrange them into rows with 7 students per row. The number of rows needed is: 28÷7 = 4 Thus, 28 students can be evenly divided into 4 rows, showing that 28 is a multiple of 7.
Example 3: Purchasing Supplies
A store sells notebooks in packs of 7. If you need 49 notebooks for a school project, you will buy: 49÷7 = 7 This means you need 7 packs of notebooks, as 49 is a multiple of 7.
Example 4: Budgeting and Savings
If you save $7 every week, after 10 weeks you will have: 7×10 = 70 This shows how consistent savings in multiples of 7 can help in budgeting and reaching financial goals.
Example 5: Athletic Training
In training sessions, a coach might schedule exercises in sets of 7. For instance, if an athlete completes 4 sets of 7 push-ups, the total number of push-ups is: 7×4 = 28This illustrates how multiples of 7 can be used to structure workouts effectively.
Example 6: Party Planning
If you are planning a party and want to create gift bags, with each bag containing 7 items, and you have 56 items in total, you can make: 56÷7 = 8 This means you can create 8 gift bags, showing that 56 is a multiple of 7.
