What is 2/31 plus 2/11? (Answer: 84/341)

Exact Answer

==================================================
Problem: What is 2/31 plus 2/11?
Formula / Expression: 2/31 + 2/11
Final Answer: 84/341
==================================================

Step-by-Step Solution:

Step 1: Find the Least Common Denominator (LCD)
The denominators 31 and 11 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 31 × 11 = 341.
Working: LCD(31, 11) = 341

Step 2: Convert to Equivalent Fractions with Common Denominator 341
Multiply the numerator and denominator of 2/31 by 11, and multiply the numerator and denominator of 2/11 by 31 so both fractions share the common base 341.
Working: 2 × 11/31 × 11 = 22/341 and 2 × 31/11 × 31 = 62/341

Step 3: Add the Numerators
Now add the numerators (22 + 62 = 84) and keep the common denominator 341 unchanged.
Working: 22 + 62/341 = 84/341

Step 4: Check if the Fraction Can Be Simplified
The Greatest Common Divisor (GCD) of 84 and 341 is 1, confirming that 84/341 cannot be reduced further—it is already in its simplest irreducible form.
Working: 84/341

Step 5: Decimal & Percentage Representation
Dividing the numerator 84 by denominator 341 produces a repeating decimal (approximately 0.246334, or 24.6334%).
Working: 84 ÷ 341 = 0.246334 (24.6334%)

Key Values:
- Simplified Fraction: 84/341
- Mixed Number Form: 84/341
- Decimal Value: 0.246334
- Percentage: 24.6334%

Step-by-Step Solution: 2/31 + 2/11

Step 1

Find the Least Common Denominator (LCD)

The denominators 31 and 11 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 31 × 11 = 341.

LCD(31, 11) = 341

Step 2

Convert to Equivalent Fractions with Common Denominator 341

Multiply the numerator and denominator of 2/31 by 11, and multiply the numerator and denominator of 2/11 by 31 so both fractions share the common base 341.

2 × 11/31 × 11 = 22/341 and 2 × 31/11 × 31 = 62/341

Step 3

Add the Numerators

Now add the numerators (22 + 62 = 84) and keep the common denominator 341 unchanged.

22 + 62/341 = 84/341

Step 4

Check if the Fraction Can Be Simplified

The Greatest Common Divisor (GCD) of 84 and 341 is 1, confirming that 84/341 cannot be reduced further—it is already in its simplest irreducible form.

84/341

Step 5

Decimal & Percentage Representation
