What is 4/33 plus 2/9? (Answer: 34/99)

Exact Answer

==================================================
Problem: What is 4/33 plus 2/9?
Formula / Expression: 4/33 + 2/9
Final Answer: 34/99
==================================================

Step-by-Step Solution:

Step 1: Find the Least Common Denominator (LCD)
The denominators 33 and 9 share a common factor (GCD = 3). Finding their Least Common Multiple gives an LCD of 99 (which is smaller than their product 33 × 9 = 297, keeping the calculation simpler).
Working: LCD(33, 9) = 99

Step 2: Convert to Equivalent Fractions with Common Denominator 99
Multiply the numerator and denominator of 4/33 by 3, and multiply the numerator and denominator of 2/9 by 11 so both fractions share the common base 99.
Working: 4 × 3/33 × 3 = 12/99 and 2 × 11/9 × 11 = 22/99

Step 3: Add the Numerators
Now add the numerators (12 + 22 = 34) and keep the common denominator 99 unchanged.
Working: 12 + 22/99 = 34/99

Step 4: Check if the Fraction Can Be Simplified
The Greatest Common Divisor (GCD) of 34 and 99 is 1, confirming that 34/99 cannot be reduced further—it is already in its simplest irreducible form.
Working: 34/99

Step 5: Decimal & Percentage Representation
Dividing the numerator 34 by denominator 99 produces a repeating decimal (approximately 0.343434, or 34.3434%).
Working: 34 ÷ 99 = 0.343434 (34.3434%)

Key Values:
- Simplified Fraction: 34/99
- Mixed Number Form: 34/99
- Decimal Value: 0.343434
