Exact Answer

==================================================
Problem: What is 4/52 plus 11/21?
Formula / Expression: 4/52 + 11/21
Final Answer: 164/273
==================================================

Step-by-Step Solution:

Step 1: Find the Least Common Denominator (LCD)
The denominators 52 and 21 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 52 × 21 = 1092.
Working: LCD(52, 21) = 1092

Step 2: Convert to Equivalent Fractions with Common Denominator 1092
Multiply the numerator and denominator of 4/52 by 21, and multiply the numerator and denominator of 11/21 by 52 so both fractions share the common base 1092.
Working: 4 × 21/52 × 21 = 84/1092 and 11 × 52/21 × 52 = 572/1092

Step 3: Add the Numerators
Now add the numerators (84 + 572 = 656) and keep the common denominator 1092 unchanged.
Working: 84 + 572/1092 = 656/1092

Step 4: Simplify the Fraction to Lowest Terms
Find the Greatest Common Divisor (GCD) of 656 and 1092, which is 4. Divide both the numerator and denominator by 4.
Working: 656 ÷ 4/1092 ÷ 4 = 164/273

Step 5: Decimal & Percentage Representation
Dividing the numerator 164 by denominator 273 produces a repeating decimal (approximately 0.600733, or 60.0733%).
Working: 164 ÷ 273 = 0.600733 (60.0733%)

Key Values:
- Simplified Fraction: 164/273
- Mixed Number Form: 164/273
- Decimal Value: 0.600733
- Percentage: 60.0733%

Step-by-Step Solution: 4/52 + 11/21

Step 1

Find the Least Common Denominator (LCD)

The denominators 52 and 21 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 52 × 21 = 1092.

LCD(52, 21) = 1092

Step 2

Convert to Equivalent Fractions with Common Denominator 1092

Multiply the numerator and denominator of 4/52 by 21, and multiply the numerator and denominator of 11/21 by 52 so both fractions share the common base 1092.

4 × 21/52 × 21 = 84/1092 and 11 × 52/21 × 52 = 572/1092

Step 3

Add the Numerators

Now add the numerators (84 + 572 = 656) and keep the common denominator 1092 unchanged.

84 + 572/1092 = 656/1092

Step 4

Simplify the Fraction to Lowest Terms

Find the Greatest Common Divisor (GCD) of 656 and 1092, which is 4. Divide both the numerator and denominator by 4.

656 ÷ 4/1092 ÷ 4 = 164/273

Step 5

Decimal & Percentage Representation

Dividing the numerator 164 by denominator 273 produces a repeating decimal (approximately 0.600733, or 60.0733%).

164 ÷ 273 = 0.600733 (60.0733%)
