What is 3/22 plus 2/3? (Answer: 53/66)

Exact Answer

==================================================
Problem: What is 3/22 plus 2/3?
Formula / Expression: 3/22 + 2/3
Final Answer: 53/66
==================================================

Step-by-Step Solution:

Step 1: Find the Least Common Denominator (LCD)
The denominators 22 and 3 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 22 × 3 = 66.
Working: LCD(22, 3) = 66

Step 2: Convert to Equivalent Fractions with Common Denominator 66
Multiply the numerator and denominator of 3/22 by 3, and multiply the numerator and denominator of 2/3 by 22 so both fractions share the common base 66.
Working: 3 × 3/22 × 3 = 9/66 and 2 × 22/3 × 22 = 44/66

Step 3: Add the Numerators
Now add the numerators (9 + 44 = 53) and keep the common denominator 66 unchanged.
Working: 9 + 44/66 = 53/66

Step 4: Check if the Fraction Can Be Simplified
The Greatest Common Divisor (GCD) of 53 and 66 is 1, confirming that 53/66 cannot be reduced further—it is already in its simplest irreducible form.
Working: 53/66

Step 5: Decimal & Percentage Representation
Dividing the numerator 53 by denominator 66 produces a repeating decimal (approximately 0.80303, or 80.303%).
Working: 53 ÷ 66 = 0.80303 (80.303%)

Key Values:
- Simplified Fraction: 53/66
- Mixed Number Form: 53/66
- Decimal Value: 0.80303
- Percentage: 80.303%

Step-by-Step Solution: 3/22 + 2/3

Step 1

Find the Least Common Denominator (LCD)

The denominators 22 and 3 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 22 × 3 = 66.

LCD(22, 3) = 66

Step 2

Convert to Equivalent Fractions with Common Denominator 66

Multiply the numerator and denominator of 3/22 by 3, and multiply the numerator and denominator of 2/3 by 22 so both fractions share the common base 66.

3 × 3/22 × 3 = 9/66 and 2 × 22/3 × 22 = 44/66

Step 3

Add the Numerators

Now add the numerators (9 + 44 = 53) and keep the common denominator 66 unchanged.

9 + 44/66 = 53/66

Step 4

Check if the Fraction Can Be Simplified

The Greatest Common Divisor (GCD) of 53 and 66 is 1, confirming that 53/66 cannot be reduced further—it is already in its simplest irreducible form.

53/66

Step 5

Decimal & Percentage Representation

Dividing the numerator 53 by denominator 66 produces a repeating decimal (approximately 0.80303, or 80.303%).
