What is 2/8 plus 5/6? (Answer: 13/12)

Exact Answer

==================================================
Problem: What is 2/8 plus 5/6?
Formula / Expression: 2/8 + 5/6
Final Answer: 1 1/12 (13/12)
==================================================

Step-by-Step Solution:

Step 1: Find the Least Common Denominator (LCD)
The denominators 8 and 6 share a common factor (GCD = 2). Finding their Least Common Multiple gives an LCD of 24 (which is smaller than their product 8 × 6 = 48, keeping the calculation simpler).
Working: LCD(8, 6) = 24

Step 2: Convert to Equivalent Fractions with Common Denominator 24
Multiply the numerator and denominator of 2/8 by 3, and multiply the numerator and denominator of 5/6 by 4 so both fractions share the common base 24.
Working: 2 × 3/8 × 3 = 6/24 and 5 × 4/6 × 4 = 20/24

Step 3: Add the Numerators
Now add the numerators (6 + 20 = 26) and keep the common denominator 24 unchanged.
Working: 6 + 20/24 = 26/24

Step 4: Simplify the Fraction to Lowest Terms
Find the Greatest Common Divisor (GCD) of 26 and 24, which is 2. Divide both the numerator and denominator by 2.
Working: 26 ÷ 2/24 ÷ 2 = 13/12

Step 5: Convert Improper Fraction to a Mixed Number
Since the numerator (13) is greater than the denominator (12), divide 13 by 12: it goes in 1 whole time(s) with a remainder of 1, giving the mixed number 1 1/12.
Working: 13/12 = 1 1/12

Step 6: Decimal & Percentage Representation
Dividing the numerator 13 by denominator 12 produces a repeating decimal (approximately 1.083333, or 108.3333%).
Working: 13 ÷ 12 = 1.083333 (108.3333%)

Key Values:
- Simplified Fraction: 13/12
- Mixed Number Form: 1 1/12
- Decimal Value: 1.083333
- Percentage: 108.3333%

Step-by-Step Solution: 2/8 + 5/6

Step 1

Find the Least Common Denominator (LCD)

The denominators 8 and 6 share a common factor (GCD = 2). Finding their Least Common Multiple gives an LCD of 24 (which is smaller than their product 8 × 6 = 48, keeping the calculation simpler).

LCD(8, 6) = 24

Step 2

Convert to Equivalent Fractions with Common Denominator 24

Multiply the numerator and denominator of 2/8 by 3, and multiply the numerator and denominator of 5/6 by 4 so both fractions share the common base 24.

2 × 3/8 × 3 = 6/24 and 5 × 4/6 × 4 = 20/24

Step 3

Add the Numerators

Now add the numerators (6 + 20 = 26) and keep the common denominator 24 unchanged.

6 + 20/24 = 26/24

Step 4

Simplify the Fraction to Lowest Terms

Find the Greatest Common Divisor (GCD) of 26 and 24, which is 2. Divide both the numerator and denominator by 2.

26 ÷ 2/24 ÷ 2 = 13/12

Step 5

Convert Improper Fraction to a Mixed Number

Since the numerator (13) is greater than the denominator (12), divide 13 by 12: it goes in 1 whole time(s) with a remainder of 1, giving the mixed number 1 1/12.

13/12 = 11/12

Step 6

Decimal & Percentage Representation

Dividing the numerator 13 by denominator 12 produces a repeating decimal (approximately 1.083333, or 108.3333%).

13 ÷ 12 = 1.083333 (108.3333%)
