What is 2/3 plus 2/3? (Answer: 4/3)

Exact Answer

==================================================
Problem: What is 2/3 plus 2/3?
Formula / Expression: 2/3 + 2/3
Final Answer: 1 1/3 (4/3)
==================================================

Step-by-Step Solution:

Step 1: Check the Denominators (Like Fractions)
Both fractions already share the identical denominator (3). Because these are like fractions, no conversion to a common denominator is required—we directly add their numerators while keeping the denominator 3.
Working: 2/3 + 2/3

Step 2: Add the Numerators
Now add the numerators (2 + 2 = 4) and keep the common denominator 3 unchanged.
Working: 2 + 2/3 = 4/3

Step 3: Check if the Fraction Can Be Simplified
The Greatest Common Divisor (GCD) of 4 and 3 is 1, confirming that 4/3 cannot be reduced further—it is already in its simplest irreducible form.
Working: 4/3

Step 4: Convert Improper Fraction to a Mixed Number
Since the numerator (4) is greater than the denominator (3), divide 4 by 3: it goes in 1 whole time(s) with a remainder of 1, giving the mixed number 1 1/3.
Working: 4/3 = 1 1/3

Step 5: Decimal & Percentage Representation
Dividing the numerator 4 by denominator 3 produces a repeating decimal (approximately 1.333333, or 133.3333%).
Working: 4 ÷ 3 = 1.333333 (133.3333%)

Key Values:
- Simplified Fraction: 4/3
- Mixed Number Form: 1 1/3
- Decimal Value: 1.333333
- Percentage: 133.3333%
