Exact Answer

==================================================
Problem: What is 10/52 plus 9/13?
Formula / Expression: 10/52 + 9/13
Final Answer: 23/26
==================================================

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 10/52 by 1, and multiply the numerator and denominator of 9/13 by 4 so both fractions share the common base 52.
Working: 10 × 1/52 × 1 = 10/52 and 9 × 4/13 × 4 = 36/52

Step 3: Add the Numerators
Now add the numerators (10 + 36 = 46) and keep the common denominator 52 unchanged.
Working: 10 + 36/52 = 46/52

Step 4: Simplify the Fraction to Lowest Terms
Find the Greatest Common Divisor (GCD) of 46 and 52, which is 2. Divide both the numerator and denominator by 2.
Working: 46 ÷ 2/52 ÷ 2 = 23/26

Step 5: Decimal & Percentage Representation
Dividing the numerator 23 by denominator 26 produces a repeating decimal (approximately 0.884615, or 88.4615%).
Working: 23 ÷ 26 = 0.884615 (88.4615%)
