• 182: 91 × 2 = 182
• 273: 91 × 3 = 273

Larger Multiples

• 910: 91 × 10 = 910
• 1820: 91 × 20 = 1820
• 2730: 91 × 30 = 2730

## Real-Life Examples

• Time: 5460 seconds in 1.5 hours is a multiple of 91 because 91 × 60 = 5460.
• Money: \$91 is a multiple of 91 because 91 × 1 = 91.
• Measurements: 8190 inches in 682.5 feet is a multiple of 91 because 91 × 90 = 8190.

## Practical Examples of Multiples of 91

1. Time: Calculate the number of seconds in 1.5 hours.
• 1.5 hours × 3600 seconds/hour = 5400 seconds.
• 5400 seconds is a multiple of 91 because 91 × 60 = 5460.
2. Money: Determine if \$455 is a multiple of 91.
• \$455 ÷ 91 = 5.
• 91 × 5 = 455, so \$455 is a multiple of 91.
3. Measurements: Find out if 1820 inches is a multiple of 91.
• 1820 inches ÷ 91 = 20.
• 91 × 20 = 1820, so 1820 inches is a multiple of 91.
4. Group Size: Check if 819 people can be grouped into 91.
• 819 ÷ 91 = 9.
• 91 × 9 = 819, so 819 people can be grouped into 91.
5. Inventory: Verify if 364 items can be packed in boxes of 91.
• 364 ÷ 91 = 4.
• 91 × 4 = 364, so 364 items can be packed in boxes of 91.

## Practical Applications
