What is 2/6 plus 9/20? (Answer: 47/60)

Exact Answer

==================================================
Problem: What is 2/6 plus 9/20?
Formula / Expression: 2/6 + 9/20
Final Answer: 47/60
==================================================

Step-by-Step Solution:

Step 1: Find the Least Common Denominator (LCD)
The denominators 6 and 20 share a common factor (GCD = 2). Finding their Least Common Multiple gives an LCD of 60 (which is smaller than their product 6 × 20 = 120, keeping the calculation simpler).
Working: LCD(6, 20) = 60

Step 2: Convert to Equivalent Fractions with Common Denominator 60
Multiply the numerator and denominator of 2/6 by 10, and multiply the numerator and denominator of 9/20 by 3 so both fractions share the common base 60.
Working: 2 × 10/6 × 10 = 20/60 and 9 × 3/20 × 3 = 27/60

Step 3: Add the Numerators
Now add the numerators (20 + 27 = 47) and keep the common denominator 60 unchanged.
Working: 20 + 27/60 = 47/60

Step 4: Check if the Fraction Can Be Simplified
The Greatest Common Divisor (GCD) of 47 and 60 is 1, confirming that 47/60 cannot be reduced further—it is already in its simplest irreducible form.
Working: 47/60

Step 5: Decimal & Percentage Representation
Dividing the numerator 47 by denominator 60 produces a repeating decimal (approximately 0.783333, or 78.3333%).
Working: 47 ÷ 60 = 0.783333 (78.3333%)

Key Values:
- Simplified Fraction: 47/60
- Mixed Number Form: 47/60
- Decimal Value: 0.783333
- Percentage: 78.3333%
