What is 9/30 plus 2/6? (Answer: 19/30)

Exact Answer

==================================================
Problem: What is 9/30 plus 2/6?
Formula / Expression: 9/30 + 2/6
Final Answer: 19/30
==================================================

Step-by-Step Solution:

Step 1: Find the Least Common Denominator (LCD)
Notice that 30 is an exact multiple of 6 (6 × 5 = 30). The Least Common Denominator (LCD) is simply 30, meaning we only need to scale one fraction.
Working: LCD(30, 6) = 30

Step 2: Convert to Equivalent Fractions with Common Denominator 30
Multiply the numerator and denominator of 9/30 by 1, and multiply the numerator and denominator of 2/6 by 5 so both fractions share the common base 30.
Working: 9 × 1/30 × 1 = 9/30 and 2 × 5/6 × 5 = 10/30

Step 3: Add the Numerators
Now add the numerators (9 + 10 = 19) and keep the common denominator 30 unchanged.
Working: 9 + 10/30 = 19/30

Step 4: Check if the Fraction Can Be Simplified
The Greatest Common Divisor (GCD) of 19 and 30 is 1, confirming that 19/30 cannot be reduced further—it is already in its simplest irreducible form.
Working: 19/30

Step 5: Decimal & Percentage Representation
Dividing the numerator 19 by denominator 30 produces a repeating decimal (approximately 0.633333, or 63.3333%).
Working: 19 ÷ 30 = 0.633333 (63.3333%)

Key Values:
- Simplified Fraction: 19/30
- Mixed Number Form: 19/30
- Decimal Value: 0.633333
- Percentage: 63.3333%
