What is 2/6 plus 9/15? (Answer: 14/15)

Exact Answer

==================================================
Problem: What is 2/6 plus 9/15?
Formula / Expression: 2/6 + 9/15
Final Answer: 14/15
==================================================

Step-by-Step Solution:

Step 1: Find the Least Common Denominator (LCD)
The denominators 6 and 15 share a common factor (GCD = 3). Finding their Least Common Multiple gives an LCD of 30 (which is smaller than their product 6 × 15 = 90, keeping the calculation simpler).
Working: LCD(6, 15) = 30

Step 2: Convert to Equivalent Fractions with Common Denominator 30
Multiply the numerator and denominator of 2/6 by 5, and multiply the numerator and denominator of 9/15 by 2 so both fractions share the common base 30.
Working: 2 × 5/6 × 5 = 10/30 and 9 × 2/15 × 2 = 18/30

Step 3: Add the Numerators
Now add the numerators (10 + 18 = 28) and keep the common denominator 30 unchanged.
Working: 10 + 18/30 = 28/30

Step 4: Simplify the Fraction to Lowest Terms
Find the Greatest Common Divisor (GCD) of 28 and 30, which is 2. Divide both the numerator and denominator by 2.
Working: 28 ÷ 2/30 ÷ 2 = 14/15

Step 5: Decimal & Percentage Representation
Dividing the numerator 14 by denominator 15 produces a repeating decimal (approximately 0.933333, or 93.3333%).
Working: 14 ÷ 15 = 0.933333 (93.3333%)

Key Values:
- Simplified Fraction: 14/15
- Mixed Number Form: 14/15
- Decimal Value: 0.933333
- Percentage: 93.3333%

The denominators 6 and 15 share a common factor (GCD = 3). Finding their Least Common Multiple gives an LCD of 30 (which is smaller than their product 6 × 15 = 90, keeping the calculation simpler).

LCD(6, 15) = 30

Step 2

Convert to Equivalent Fractions with Common Denominator 30

Multiply the numerator and denominator of 2/6 by 5, and multiply the numerator and denominator of 9/15 by 2 so both fractions share the common base 30.

2 × 5/6 × 5 = 10/30 and 9 × 2/15 × 2 = 18/30

Step 3

Add the Numerators

Now add the numerators (10 + 18 = 28) and keep the common denominator 30 unchanged.

10 + 18/30 = 28/30

Step 4

Simplify the Fraction to Lowest Terms

Find the Greatest Common Divisor (GCD) of 28 and 30, which is 2. Divide both the numerator and denominator by 2.

28 ÷ 2/30 ÷ 2 = 14/15

Step 5
