Exact Answer

==================================================
Problem: What is 4/52 plus 8/13?
Formula / Expression: 4/52 + 8/13
Final Answer: 9/13
==================================================

Step-by-Step Solution:

Step 1: Find the Least Common Denominator (LCD)
Notice that 52 is an exact multiple of 13 (13 × 4 = 52). The Least Common Denominator (LCD) is simply 52, meaning we only need to scale one fraction.
Working: LCD(52, 13) = 52

Step 2: Convert to Equivalent Fractions with Common Denominator 52
Multiply the numerator and denominator of 4/52 by 1, and multiply the numerator and denominator of 8/13 by 4 so both fractions share the common base 52.
Working: 4 × 1/52 × 1 = 4/52 and 8 × 4/13 × 4 = 32/52

Step 3: Add the Numerators
Now add the numerators (4 + 32 = 36) and keep the common denominator 52 unchanged.
Working: 4 + 32/52 = 36/52

Step 4: Simplify the Fraction to Lowest Terms
Find the Greatest Common Divisor (GCD) of 36 and 52, which is 4. Divide both the numerator and denominator by 4.
Working: 36 ÷ 4/52 ÷ 4 = 9/13

Step 5: Decimal & Percentage Representation
Dividing the numerator 9 by denominator 13 produces a repeating decimal (approximately 0.692308, or 69.2308%).
Working: 9 ÷ 13 = 0.692308 (69.2308%)

Key Values:
- Simplified Fraction: 9/13
- Mixed Number Form: 9/13
- Decimal Value: 0.692308
- Percentage: 69.2308%

Find the Least Common Denominator (LCD)

Notice that 52 is an exact multiple of 13 (13 × 4 = 52). The Least Common Denominator (LCD) is simply 52, meaning we only need to scale one fraction.

LCD(52, 13) = 52

Step 2

Convert to Equivalent Fractions with Common Denominator 52

Multiply the numerator and denominator of 4/52 by 1, and multiply the numerator and denominator of 8/13 by 4 so both fractions share the common base 52.

4 × 1/52 × 1 = 4/52 and 8 × 4/13 × 4 = 32/52

Step 3

Add the Numerators

Now add the numerators (4 + 32 = 36) and keep the common denominator 52 unchanged.

4 + 32/52 = 36/52

Step 4

Simplify the Fraction to Lowest Terms

Find the Greatest Common Divisor (GCD) of 36 and 52, which is 4. Divide both the numerator and denominator by 4.

36 ÷ 4/52 ÷ 4 = 9/13

Step 5
