What is 2/39 plus 2/9? (Answer: 32/117)

Exact Answer

==================================================
Problem: What is 2/39 plus 2/9?
Formula / Expression: 2/39 + 2/9
Final Answer: 32/117
==================================================

Step-by-Step Solution:

Step 1: Find the Least Common Denominator (LCD)
The denominators 39 and 9 share a common factor (GCD = 3). Finding their Least Common Multiple gives an LCD of 117 (which is smaller than their product 39 × 9 = 351, keeping the calculation simpler).
Working: LCD(39, 9) = 117

Step 2: Convert to Equivalent Fractions with Common Denominator 117
Multiply the numerator and denominator of 2/39 by 3, and multiply the numerator and denominator of 2/9 by 13 so both fractions share the common base 117.
Working: 2 × 3/39 × 3 = 6/117 and 2 × 13/9 × 13 = 26/117

Step 3: Add the Numerators
Now add the numerators (6 + 26 = 32) and keep the common denominator 117 unchanged.
Working: 6 + 26/117 = 32/117

Step 4: Check if the Fraction Can Be Simplified
The Greatest Common Divisor (GCD) of 32 and 117 is 1, confirming that 32/117 cannot be reduced further—it is already in its simplest irreducible form.
Working: 32/117

Step 5: Decimal & Percentage Representation
Dividing the numerator 32 by denominator 117 produces a repeating decimal (approximately 0.273504, or 27.3504%).
Working: 32 ÷ 117 = 0.273504 (27.3504%)

Key Values:
- Simplified Fraction: 32/117
- Mixed Number Form: 32/117
- Decimal Value: 0.273504

The denominators 39 and 9 share a common factor (GCD = 3). Finding their Least Common Multiple gives an LCD of 117 (which is smaller than their product 39 × 9 = 351, keeping the calculation simpler).

LCD(39, 9) = 117

Step 2

Convert to Equivalent Fractions with Common Denominator 117

Multiply the numerator and denominator of 2/39 by 3, and multiply the numerator and denominator of 2/9 by 13 so both fractions share the common base 117.

2 × 3/39 × 3 = 6/117 and 2 × 13/9 × 13 = 26/117

Step 3

Add the Numerators

Now add the numerators (6 + 26 = 32) and keep the common denominator 117 unchanged.

6 + 26/117 = 32/117

Step 4

Check if the Fraction Can Be Simplified

The Greatest Common Divisor (GCD) of 32 and 117 is 1, confirming that 32/117 cannot be reduced further—it is already in its simplest irreducible form.
