What Is a Ratio?

A ratio compares two or more quantities by division.

It shows how much of one quantity exists compared to another.

• Example: If there are:
  • 4 apples
  • 2 oranges
  • The ratio of apples to oranges is:
  • 4 : 2

This means for every 4 apples, there are 2 oranges.

How to Write a Ratio

A ratio can be written in three ways:

• Using colon → 4 : 2
• As a fraction → 4/2
• Using words → 4 to 2

All three forms represent the same comparison.

How to Simplify a Ratio

To simplify a ratio, divide both numbers by their Greatest Common Divisor (GCD).

Simplify 8 : 4

• Step 1: Find GCD of 8 and 4
• GCD = 4
• Step 2: Divide both numbers by 4
• 8 ÷ 4 : 4 ÷ 4 = 2 : 1

Simplified ratio = 2 : 1

Ratio Formula : There is no complex formula for ratio. It is simply:

Ratio = Quantity 1 ÷ Quantity 2

Or written as:

a : b

• Where: a and b are numbers being compared

Real-Life Examples of Ratio

Ratios are used in everyday life.

Classroom Example: If there are:

• 12 boys
• 18 girls

• Ratio of boys to girls:
• 12 : 18

Simplify:

• Divide by 6
• 2 : 3

Cooking Example: If a recipe uses:

• 2 cups flour
• 1 cup sugar
• Ratio of flour to sugar: 2 : 1

Speed Example: If a car travels:

• 60 km in 2 hours
• Ratio of distance to time: 60 : 2 = 30 : 1

Ratio vs Proportion

Many students confuse ratio with proportion.

• Ratio: Compares two numbers.
  • Example:
  • 3 : 5
• Proportion: Shows two ratios are equal.
  • Example:
  • 3 : 5 = 6 : 10
  • Proportion is built using ratios.

Ratio and Average (Connection)

Ratios are often used when calculating averages.

Example: If marks are in ratio 2:3:5 and total marks are 100:

• Step 1: Add ratio parts
  • 2 + 3 + 5 = 10
• Step 2: Divide total by 10
  • 100 ÷ 10 = 10
• Step 3: Multiply each part
  • 2 × 10 = 20
  • 3 × 10 = 30
  • 5 × 10 = 50

Why Ratio Is Important

Ratio helps in:

• Mathematics exams
• Business profit sharing
• Recipe measurements
• Map scaling
• Financial planning

Understanding ratios improves logical thinking skills.

Common Ratio Mistakes

• Not simplifying the ratio
• Writing numbers in wrong order
• Forgetting to divide both numbers
• Always check if the ratio can be simplified.
