What is 2/31 plus 2/3? (Answer: 68/93)

Exact Answer

==================================================
Problem: What is 2/31 plus 2/3?
Formula / Expression: 2/31 + 2/3
Final Answer: 68/93
==================================================

Step-by-Step Solution:

Step 1: Find the Least Common Denominator (LCD)
The denominators 31 and 3 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 31 × 3 = 93.
Working: LCD(31, 3) = 93

Step 2: Convert to Equivalent Fractions with Common Denominator 93
Multiply the numerator and denominator of 2/31 by 3, and multiply the numerator and denominator of 2/3 by 31 so both fractions share the common base 93.
Working: 2 × 3/31 × 3 = 6/93 and 2 × 31/3 × 31 = 62/93

Step 3: Add the Numerators
Now add the numerators (6 + 62 = 68) and keep the common denominator 93 unchanged.
Working: 6 + 62/93 = 68/93

Step 4: Check if the Fraction Can Be Simplified
The Greatest Common Divisor (GCD) of 68 and 93 is 1, confirming that 68/93 cannot be reduced further—it is already in its simplest irreducible form.
Working: 68/93

Step 5: Decimal & Percentage Representation
Dividing the numerator 68 by denominator 93 produces a repeating decimal (approximately 0.731183, or 73.1183%).
Working: 68 ÷ 93 = 0.731183 (73.1183%)

Key Values:
- Simplified Fraction: 68/93
- Mixed Number Form: 68/93
- Decimal Value: 0.731183
- Percentage: 73.1183%

Step-by-Step Solution: 2/31 + 2/3

Step 1

Find the Least Common Denominator (LCD)

The denominators 31 and 3 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 31 × 3 = 93.

LCD(31, 3) = 93

Step 2

Convert to Equivalent Fractions with Common Denominator 93

Multiply the numerator and denominator of 2/31 by 3, and multiply the numerator and denominator of 2/3 by 31 so both fractions share the common base 93.

2 × 3/31 × 3 = 6/93 and 2 × 31/3 × 31 = 62/93

Step 3

Add the Numerators

Now add the numerators (6 + 62 = 68) and keep the common denominator 93 unchanged.

6 + 62/93 = 68/93

Step 4

Check if the Fraction Can Be Simplified

The Greatest Common Divisor (GCD) of 68 and 93 is 1, confirming that 68/93 cannot be reduced further—it is already in its simplest irreducible form.
