Exact Answer

==================================================
Problem: What is 8/26 plus 9/13?
Formula / Expression: 8/26 + 9/13
Final Answer: 1
==================================================

Step-by-Step Solution:

Step 1: Find the Least Common Denominator (LCD)
Notice that 26 is an exact multiple of 13 (13 × 2 = 26). The Least Common Denominator (LCD) is simply 26, meaning we only need to scale one fraction.
Working: LCD(26, 13) = 26

Step 2: Convert to Equivalent Fractions with Common Denominator 26
Multiply the numerator and denominator of 8/26 by 1, and multiply the numerator and denominator of 9/13 by 2 so both fractions share the common base 26.
Working: 8 × 1/26 × 1 = 8/26 and 9 × 2/13 × 2 = 18/26

Step 3: Add the Numerators
Now add the numerators (8 + 18 = 26) and keep the common denominator 26 unchanged.
Working: 8 + 18/26 = 26/26

Step 4: Simplify to an Exact Whole Number
Notice that the numerator (26) is completely divisible by the denominator (26). Dividing 26 by 26 yields the whole number 1 with zero remainder.
Working: 26/26 = 1

Step 5: Decimal & Percentage Representation
Dividing the numerator 1 by denominator 1 yields an exact terminating decimal of 1 (or 100%).
Working: 1 ÷ 1 = 1 (100%)
