Ratio Simplifier

Use our free ratio simplifier to reduce any ratio (A : B) to its lowest terms by dividing both parts by their greatest common factor. Shows equivalent ratios (2x-10x), decimal form, fraction form, and percentage.

Math

A (left)

B (right)

Formula

Simplify any ratio to its lowest terms by dividing both sides by their greatest common factor (GCF). Also shows the decimal form, fraction form, percentage, and 9 equivalent ratios (2x through 10x).

A : B → (A÷GCF) : (B÷GCF)

Percentage: The percentage value you want to apply

Number: The original number or value

Result: The calculated result

How It Works

1Enter the two numbers of the ratio (both positive).
2Click Calculate to see the simplified ratio and all related forms.

Examples

12 : 8

1.GCF(12, 8) = 4, so 12÷4 : 8÷4 = 3 : 2

Result: 3 : 2

100 : 75

1.GCF(100, 75) = 25, so 100÷25 : 75÷25 = 4 : 3

Result: 4 : 3
