## Multiples of 85

Multiples of 85 are numbers that can be expressed as (85 x n), where (n) is an integer. These multiples increase by 85 each time (e.g., 85, 170, 255, 340, 425) and are not necessarily even. Understanding multiples of 85 is crucial in mathematics, particularly in algebraic concepts, squares, square roots, and fractions. They help in recognizing number properties and performing arithmetic operations efficiently. Recognizing these multiples aids in grasping complex mathematical ideas and solving algebraic equations. Multiples serve as essential building blocks in number theory, helping to explore patterns, relationships, and the behavior of numbers within mathematical frameworks. This knowledge is fundamental for mastering advanced mathematical concepts and operations.

## Examples on Multiples of 85

Simple Multiples:

• 85: 85 × 1 = 85
• 170: 85 × 2 = 170
• 255: 85 × 3 = 255

Larger Multiples:

• 425: 85 × 5 = 425
• 850: 85 × 10 = 850
• 1700: 85 × 20 = 1700

## Real-Life Examples

Time : 5100 seconds in 85 minutes is a multiple of 85 because 85 × 60 = 5100.

Money : \$425 is a multiple of 85 because 85 × 5 = 425.

Measurements : 3400 inches is a multiple of 85 because 85 × 40 = 3400.

## Practical Examples of Multiples of 85

1. Time Calculation: To find the total seconds in 85 minutes, multiply 85 by 60.
• 85 × 60 = 5100 seconds
2. Budgeting: If each item costs \$85, the cost for 10 items is:
• 85 × 10 = \$850
3. Distance: A bus travels 85 miles per hour. In 4 hours, it will cover:
• 85 × 4 = 340 miles
4. Inventory: A box holds 85 units. For 7 boxes, the total units are:
• 85 × 7 = 595 units
5. Construction: Each tile is 85 cm wide. To cover 6 meters (600 cm), you need:
• 600 ÷ 85 ≈ 7.06, so 8 tiles (rounding up).

## Practical Applications

• Counting by Eighty-Fives:
When counting by eighty-fives (85, 170, 255, 340…), you are listing the multiples of 85.
• Multiple of 85:
Any number that is a multiple of 85, such as 425 or 850, is a multiple of 85 because it can be divided evenly by 85.
