What is 2/8 plus 3/6? (Answer: 3/4)

Exact Answer

==================================================
Problem: What is 2/8 plus 3/6?
Formula / Expression: 2/8 + 3/6
Final Answer: 3/4
==================================================

Step-by-Step Solution:

Step 1: Find the Least Common Denominator (LCD)
The denominators 8 and 6 share a common factor (GCD = 2). Finding their Least Common Multiple gives an LCD of 24 (which is smaller than their product 8 × 6 = 48, keeping the calculation simpler).
Working: LCD(8, 6) = 24

Step 2: Convert to Equivalent Fractions with Common Denominator 24
Multiply the numerator and denominator of 2/8 by 3, and multiply the numerator and denominator of 3/6 by 4 so both fractions share the common base 24.
Working: 2 × 3/8 × 3 = 6/24 and 3 × 4/6 × 4 = 12/24

Step 3: Add the Numerators
Now add the numerators (6 + 12 = 18) and keep the common denominator 24 unchanged.
Working: 6 + 12/24 = 18/24

Step 4: Simplify the Fraction to Lowest Terms
Find the Greatest Common Divisor (GCD) of 18 and 24, which is 6. Divide both the numerator and denominator by 6.
Working: 18 ÷ 6/24 ÷ 6 = 3/4

Step 5: Decimal & Percentage Representation
Dividing the numerator 3 by denominator 4 yields an exact terminating decimal of 0.75 (or 75%).
Working: 3 ÷ 4 = 0.75 (75%)

Key Values:
- Simplified Fraction: 3/4
- Mixed Number Form: 3/4
- Decimal Value: 0.75
- Percentage: 75%
