About This Worksheet

This medium-level worksheet contains 18 problems designed for 6th Grade students practicing understanding ratios. Medium worksheets introduce larger numbers and varied question formats to deepen understanding and build fluency.

Ratios are the language of comparison in mathematics and everyday life. Mastering ratio notation and meaning unlocks proportional reasoning — the backbone of percents, scale, probability, and algebra.

  • Write ratios in three forms: fraction, colon, and word form
  • Understand a ratio as a comparison of two quantities
  • Identify part-to-part and part-to-whole ratios
  • Simplify ratios to lowest terms using common factors
  • Recognize equivalent ratios in real-world contexts like recipes

How to Solve: Worked Example

Example Problem: Simplify the ratio 12:8.
Solution Steps:
  1. Find the greatest common factor (GCF) of 12 and 8.
  2. GCF of 12 and 8 is 4.
  3. Divide both numbers by 4: 12 ÷ 4 = 3, 8 ÷ 4 = 2.
  4. The simplified ratio is 3:2.
Answer: 3:2
Tip: Simplify ratios by dividing both parts by their GCF, just like simplifying fractions.
