Proportions Worksheets for Grade 4
Proportions worksheets for grade 4. Printable practice sheets with answer keys.
Understanding the Concept
A proportion is an equation stating that two ratios are equal. Proportions help us solve problems involving scaling, similar figures, and equivalent relationships.
Key Proportion Concepts
- 1Proportion: a/b = c/d (two equal ratios)
- 2Cross multiplication: ad = bc
- 3Setting up proportions from word problems
- 4Scale factor in similar figures
- 5Direct and inverse proportions
- 6Unit rate method for solving
⚠️ Common Mistakes to Avoid
- •Setting up proportion with inconsistent units
- •Cross multiplying incorrectly
- •Using wrong ratio order
- •Confusing direct and inverse proportion
- •Not labeling what each number represents
🌍 Real-World Applications
- •Converting recipes for different servings
- •Map reading and distance calculations
- •Currency exchange
- •Scale models and drawings
- •Photography enlargement/reduction
Sample Practice Problems
Q1: If 4 tickets cost $36, how much for 7 tickets?
Show Answer & Explanation
Answer: $63
Unit rate: $36 ÷ 4 = $9 each. 7 × $9 = $63
✨ Expert Study Tips
Label units to keep track of what's what
Cross multiply to solve for unknown
Check: if one increases, should the other increase too?
Set up: same units across, same units down
Verify by checking if both ratios are equal
