What is 2/57 plus 2/9? (Answer: 44/171)

Exact Answer

==================================================
Problem: What is 2/57 plus 2/9?
Formula / Expression: 2/57 + 2/9
Final Answer: 44/171
==================================================

Step-by-Step Solution:

Step 1: Find the Least Common Denominator (LCD)
The denominators 57 and 9 share a common factor (GCD = 3). Finding their Least Common Multiple gives an LCD of 171 (which is smaller than their product 57 × 9 = 513, keeping the calculation simpler).
Working: LCD(57, 9) = 171

Step 2: Convert to Equivalent Fractions with Common Denominator 171
Multiply the numerator and denominator of 2/57 by 3, and multiply the numerator and denominator of 2/9 by 19 so both fractions share the common base 171.
Working: 2 × 3/57 × 3 = 6/171 and 2 × 19/9 × 19 = 38/171

Step 3: Add the Numerators
Now add the numerators (6 + 38 = 44) and keep the common denominator 171 unchanged.
Working: 6 + 38/171 = 44/171

Step 4: Check if the Fraction Can Be Simplified
The Greatest Common Divisor (GCD) of 44 and 171 is 1, confirming that 44/171 cannot be reduced further—it is already in its simplest irreducible form.
Working: 44/171

Step 5: Decimal & Percentage Representation
Dividing the numerator 44 by denominator 171 produces a repeating decimal (approximately 0.25731, or 25.731%).
Working: 44 ÷ 171 = 0.25731 (25.731%)

Key Values:
- Simplified Fraction: 44/171
- Mixed Number Form: 44/171
- Decimal Value: 0.25731
- Percentage: 25.731%

The denominators 57 and 9 share a common factor (GCD = 3). Finding their Least Common Multiple gives an LCD of 171 (which is smaller than their product 57 × 9 = 513, keeping the calculation simpler).

LCD(57, 9) = 171

Step 2

Convert to Equivalent Fractions with Common Denominator 171

Multiply the numerator and denominator of 2/57 by 3, and multiply the numerator and denominator of 2/9 by 19 so both fractions share the common base 171.

2 × 3/57 × 3 = 6/171 and 2 × 19/9 × 19 = 38/171

Step 3

Add the Numerators

Now add the numerators (6 + 38 = 44) and keep the common denominator 171 unchanged.

6 + 38/171 = 44/171

Step 4

Check if the Fraction Can Be Simplified

The Greatest Common Divisor (GCD) of 44 and 171 is 1, confirming that 44/171 cannot be reduced further—it is already in its simplest irreducible form.
