What is 2/37 plus 2/13? (Answer: 100/481)

Exact Answer

==================================================
Problem: What is 2/37 plus 2/13?
Formula / Expression: 2/37 + 2/13
Final Answer: 100/481
==================================================

Step-by-Step Solution:

Step 1: Find the Least Common Denominator (LCD)
The denominators 37 and 13 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 37 × 13 = 481.
Working: LCD(37, 13) = 481

Step 2: Convert to Equivalent Fractions with Common Denominator 481
Multiply the numerator and denominator of 2/37 by 13, and multiply the numerator and denominator of 2/13 by 37 so both fractions share the common base 481.
Working: 2 × 13/37 × 13 = 26/481 and 2 × 37/13 × 37 = 74/481

Step 3: Add the Numerators
Now add the numerators (26 + 74 = 100) and keep the common denominator 481 unchanged.
Working: 26 + 74/481 = 100/481

Step 4: Check if the Fraction Can Be Simplified
The Greatest Common Divisor (GCD) of 100 and 481 is 1, confirming that 100/481 cannot be reduced further—it is already in its simplest irreducible form.
Working: 100/481

Step 5: Decimal & Percentage Representation
Dividing the numerator 100 by denominator 481 produces a repeating decimal (approximately 0.2079, or 20.79%).
Working: 100 ÷ 481 = 0.2079 (20.79%)

Key Values:
- Simplified Fraction: 100/481
- Mixed Number Form: 100/481
- Decimal Value: 0.2079
- Percentage: 20.79%

Step-by-Step Solution: 2/37 + 2/13

Step 1

Find the Least Common Denominator (LCD)

The denominators 37 and 13 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 37 × 13 = 481.

LCD(37, 13) = 481

Step 2

Convert to Equivalent Fractions with Common Denominator 481

Multiply the numerator and denominator of 2/37 by 13, and multiply the numerator and denominator of 2/13 by 37 so both fractions share the common base 481.

2 × 13/37 × 13 = 26/481 and 2 × 37/13 × 37 = 74/481

Step 3

Add the Numerators

Now add the numerators (26 + 74 = 100) and keep the common denominator 481 unchanged.

26 + 74/481 = 100/481

Step 4

Check if the Fraction Can Be Simplified

The Greatest Common Divisor (GCD) of 100 and 481 is 1, confirming that 100/481 cannot be reduced further—it is already in its simplest irreducible form.

100/481

Step 5

Decimal & Percentage Representation

Dividing the numerator 100 by denominator 481 produces a repeating decimal (approximately 0.2079, or 20.79%).
