Exact Answer

==================================================
Problem: What is 2/4 plus 4/8?
Formula / Expression: 2/4 + 4/8
Final Answer: 1
==================================================

Step-by-Step Solution:

Step 1: Find the Least Common Denominator (LCD)
Notice that 8 is an exact multiple of 4 (4 × 2 = 8). The Least Common Denominator (LCD) is simply 8, meaning we only need to scale one fraction.
Working: LCD(4, 8) = 8

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

Step 3: Add the Numerators
Now add the numerators (4 + 4 = 8) and keep the common denominator 8 unchanged.
Working: 4 + 4/8 = 8/8

Step 4: Simplify to an Exact Whole Number
Notice that the numerator (8) is completely divisible by the denominator (8). Dividing 8 by 8 yields the whole number 1 with zero remainder.
Working: 8/8 = 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%)
