## Important Notes

• Even Numbers : All multiples of 80 are even numbers, meaning they end in 0.
• Divisibility : A number is a multiple of 80 if it can be divided by 80 with no remainder.
• Factors : Multiples of 80 have 80 as one of their factors.
• Infinite Sequence : There are infinitely many multiples of 80, extending indefinitely as 80, 160, 240, 320, 400, and so on.
• Arithmetic Pattern : The difference between consecutive multiples of 80 is always 80.

## Examples on Multiples of 80

Simple Multiples

• 80: 80 × 1 = 80
• 160: 80 × 2 = 160
• 240: 80 × 3 = 240

Larger Multiples

• 800: 80 × 10 = 800
• 1600: 80 × 20 = 1600
• 3200: 80 × 40 = 3200

## Real-Life Examples

• Time: 60 minutes in an hour is a multiple of 80 because 80 × 0.75 = 60.
• Money: \$80 is a multiple of 80 because 80 × 1 = 80.
• Measurements: 160 inches is a multiple of 80 because 80 × 2 = 160.

## Practical Examples of Multiples of 80

1. Time Calculation: In a workweek, there are 400 minutes in a standard 8-hour day. Since 400 is a multiple of 80 (80 × 5 = 400), it helps in dividing tasks evenly.
2. Money Savings: If you save \$80 every week, in 5 weeks, you will have saved \$400. This is because 80 × 5 = 400, making budgeting simpler.
3. Construction Measurements: When building a fence, each panel might be 80 inches wide. For a fence of 640 inches, you would need 8 panels because 80 × 8 = 640.
4. Event Planning: For a large event, if each table seats 80 people, and you have 960 guests, you will need 12 tables. This is calculated as 80 × 12 = 960.
5. Packaging: A factory packages items in boxes of 80 units. If they produce 2400 units, they will need 30 boxes, since 80 × 30 = 2400.

## Practical Applications

• Counting by Eighties: When counting by eighties (80, 160, 240, 320…), you are listing the multiples of 80.
• Large Grouping: When organizing a large event, seating 1600 people into groups of 80 makes it easier to manage and distribute resources.
