What is 2/11 plus 1/3? (Answer: 17/33)

Exact Answer

==================================================
Problem: What is 2/11 plus 1/3?
Formula / Expression: 2/11 + 1/3
Final Answer: 17/33
==================================================

Step-by-Step Solution:

Step 1: Find the Least Common Denominator (LCD)
The denominators 11 and 3 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 11 × 3 = 33.
Working: LCD(11, 3) = 33

Step 2: Convert to Equivalent Fractions with Common Denominator 33
Multiply the numerator and denominator of 2/11 by 3, and multiply the numerator and denominator of 1/3 by 11 so both fractions share the common base 33.
Working: 2 × 3/11 × 3 = 6/33 and 1 × 11/3 × 11 = 11/33

Step 3: Add the Numerators
Now add the numerators (6 + 11 = 17) and keep the common denominator 33 unchanged.
Working: 6 + 11/33 = 17/33

Step 4: Check if the Fraction Can Be Simplified
The Greatest Common Divisor (GCD) of 17 and 33 is 1, confirming that 17/33 cannot be reduced further—it is already in its simplest irreducible form.
Working: 17/33

Step 5: Decimal & Percentage Representation
Dividing the numerator 17 by denominator 33 produces a repeating decimal (approximately 0.515152, or 51.5152%).
Working: 17 ÷ 33 = 0.515152 (51.5152%)

Key Values:
- Simplified Fraction: 17/33
- Mixed Number Form: 17/33
- Decimal Value: 0.515152
- Percentage: 51.5152%

Step-by-Step Solution: 2/11 + 1/3

Step 1

Find the Least Common Denominator (LCD)

The denominators 11 and 3 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 11 × 3 = 33.

LCD(11, 3) = 33

Step 2

Convert to Equivalent Fractions with Common Denominator 33

Multiply the numerator and denominator of 2/11 by 3, and multiply the numerator and denominator of 1/3 by 11 so both fractions share the common base 33.

2 × 3/11 × 3 = 6/33 and 1 × 11/3 × 11 = 11/33

Step 3

Add the Numerators

Now add the numerators (6 + 11 = 17) and keep the common denominator 33 unchanged.

6 + 11/33 = 17/33

Step 4

Check if the Fraction Can Be Simplified

The Greatest Common Divisor (GCD) of 17 and 33 is 1, confirming that 17/33 cannot be reduced further—it is already in its simplest irreducible form.
