What is 2/6 plus 4/5? (Answer: 17/15)

Exact Answer

==================================================
Problem: What is 2/6 plus 4/5?
Formula / Expression: 2/6 + 4/5
Final Answer: 1 2/15 (17/15)
==================================================

Step-by-Step Solution:

Step 1: Find the Least Common Denominator (LCD)
The denominators 6 and 5 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 6 × 5 = 30.
Working: LCD(6, 5) = 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 4/5 by 6 so both fractions share the common base 30.
Working: 2 × 5/6 × 5 = 10/30 and 4 × 6/5 × 6 = 24/30

Step 3: Add the Numerators
Now add the numerators (10 + 24 = 34) and keep the common denominator 30 unchanged.
Working: 10 + 24/30 = 34/30

Step 4: Simplify the Fraction to Lowest Terms
Find the Greatest Common Divisor (GCD) of 34 and 30, which is 2. Divide both the numerator and denominator by 2.
Working: 34 ÷ 2/30 ÷ 2 = 17/15

Step 5: Convert Improper Fraction to a Mixed Number
Since the numerator (17) is greater than the denominator (15), divide 17 by 15: it goes in 1 whole time(s) with a remainder of 2, giving the mixed number 1 2/15.
Working: 17/15 = 1 2/15

Step 6: Decimal & Percentage Representation
Dividing the numerator 17 by denominator 15 produces a repeating decimal (approximately 1.133333, or 113.3333%).
Working: 17 ÷ 15 = 1.133333 (113.3333%)

Key Values:
- Simplified Fraction: 17/15
- Mixed Number Form: 1 2/15
- Decimal Value: 1.133333
- Percentage: 113.3333%

Step-by-Step Solution: 2/6 + 4/5

Step 1

Find the Least Common Denominator (LCD)

The denominators 6 and 5 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 6 × 5 = 30.

LCD(6, 5) = 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 4/5 by 6 so both fractions share the common base 30.

2 × 5/6 × 5 = 10/30 and 4 × 6/5 × 6 = 24/30

Step 3

Add the Numerators

Now add the numerators (10 + 24 = 34) and keep the common denominator 30 unchanged.

10 + 24/30 = 34/30

Step 4

Simplify the Fraction to Lowest Terms

Find the Greatest Common Divisor (GCD) of 34 and 30, which is 2. Divide both the numerator and denominator by 2.

34 ÷ 2/30 ÷ 2 = 17/15

Step 5

Convert Improper Fraction to a Mixed Number

Since the numerator (17) is greater than the denominator (15), divide 17 by 15: it goes in 1 whole time(s) with a remainder of 2, giving the mixed number 1 2/15.

17/15 = 12/15

Step 6

Decimal & Percentage Representation

Dividing the numerator 17 by denominator 15 produces a repeating decimal (approximately 1.133333, or 113.3333%).

17 ÷ 15 = 1.133333 (113.3333%)
