What is 9/52 plus 4/13? (Answer: 25/52)

Exact Answer

==================================================
Problem: What is 9/52 plus 4/13?
Formula / Expression: 9/52 + 4/13
Final Answer: 25/52
==================================================

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 9/52 by 1, and multiply the numerator and denominator of 4/13 by 4 so both fractions share the common base 52.
Working: 9 × 1/52 × 1 = 9/52 and 4 × 4/13 × 4 = 16/52

Step 3: Add the Numerators
Now add the numerators (9 + 16 = 25) and keep the common denominator 52 unchanged.
Working: 9 + 16/52 = 25/52

Step 4: Check if the Fraction Can Be Simplified
The Greatest Common Divisor (GCD) of 25 and 52 is 1, confirming that 25/52 cannot be reduced further—it is already in its simplest irreducible form.
Working: 25/52

Step 5: Decimal & Percentage Representation
Dividing the numerator 25 by denominator 52 produces a repeating decimal (approximately 0.480769, or 48.0769%).
Working: 25 ÷ 52 = 0.480769 (48.0769%)

Key Values:
- Simplified Fraction: 25/52
- Mixed Number Form: 25/52
