What is 2/31 plus 2/4? (Answer: 35/62)

Exact Answer

==================================================
Problem: What is 2/31 plus 2/4?
Formula / Expression: 2/31 + 2/4
Final Answer: 35/62
==================================================

Step-by-Step Solution:

Step 1: Find the Least Common Denominator (LCD)
The denominators 31 and 4 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 31 × 4 = 124.
Working: LCD(31, 4) = 124

Step 2: Convert to Equivalent Fractions with Common Denominator 124
Multiply the numerator and denominator of 2/31 by 4, and multiply the numerator and denominator of 2/4 by 31 so both fractions share the common base 124.
Working: 2 × 4/31 × 4 = 8/124 and 2 × 31/4 × 31 = 62/124

Step 3: Add the Numerators
Now add the numerators (8 + 62 = 70) and keep the common denominator 124 unchanged.
Working: 8 + 62/124 = 70/124

Step 4: Simplify the Fraction to Lowest Terms
Find the Greatest Common Divisor (GCD) of 70 and 124, which is 2. Divide both the numerator and denominator by 2.
Working: 70 ÷ 2/124 ÷ 2 = 35/62

Step 5: Decimal & Percentage Representation
Dividing the numerator 35 by denominator 62 produces a repeating decimal (approximately 0.564516, or 56.4516%).
Working: 35 ÷ 62 = 0.564516 (56.4516%)

Key Values:
- Simplified Fraction: 35/62
- Mixed Number Form: 35/62
- Decimal Value: 0.564516
- Percentage: 56.4516%

Step-by-Step Solution: 2/31 + 2/4

Step 1

Find the Least Common Denominator (LCD)

The denominators 31 and 4 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 31 × 4 = 124.

LCD(31, 4) = 124

Step 2

Convert to Equivalent Fractions with Common Denominator 124

Multiply the numerator and denominator of 2/31 by 4, and multiply the numerator and denominator of 2/4 by 31 so both fractions share the common base 124.

2 × 4/31 × 4 = 8/124 and 2 × 31/4 × 31 = 62/124

Step 3

Add the Numerators

Now add the numerators (8 + 62 = 70) and keep the common denominator 124 unchanged.

8 + 62/124 = 70/124

Step 4

Simplify the Fraction to Lowest Terms

Find the Greatest Common Divisor (GCD) of 70 and 124, which is 2. Divide both the numerator and denominator by 2.

70 ÷ 2/124 ÷ 2 = 35/62

Step 5

Decimal & Percentage Representation

Dividing the numerator 35 by denominator 62 produces a repeating decimal (approximately 0.564516, or 56.4516%).

35 ÷ 62 = 0.564516 (56.4516%)
